About 50% of the offspring will show the recessive trait
About 75% of the offspring will show the dominant trait
Answer:
Explanation:
A
Assume that (B) genotype is dominant and (b) genotype is recessive: bb mates with bb. All the offspring will show the recessive trait. thus option A is correct.
What is genotype ?A genotype can be defined as the total set of heritable characters carrying genes transferred from parents to offspring; These genes involve in encoding specific features that can be physically expressed in an organism called as phenotype.
The genotypes of the gene can be represented in three form on the basis of allele arrangement such as homozygous dominant (PP), Heterozygous (Pp) and Homozygous recessive (pp).
genotyping is a method is used to determine the genotype of an individual by using biological assay and the techniques used are, DNA fragment analysis, PCR, allele-specific oligonucleotide (ASO) probes, nucleic acid hybridization, DNA microarrays or beads, and DNA sequencing.

If The RNA strand is AUG, what is the protein it produces.
Answer:
methionine
Explanation:
According to the codon chart (see the attached image), the RNA strand AUG will produce methionine as its translation product during the process of protein sysnthesis.
The table of codons is a chart that shows how genetic codes are translated into their respective amino acids during protein synthesis. The AUG codon also represents a signifier of the beginning of the translation process apart from coding for methionine.

Why might there be a competitive advantage to having a different flight initiation distance
when a bird is incubating eggs
Answer: The birds can perceive any kind of danger which can harm the eggs after laying.
Explanation:
The birds show response towards the other stimulus around them like weather conditions like excessive heat and rain and predators. Also they can sense the danger of damage to eggs by fellow members of the species. The distance at which the birds fly from the danger is the flight initiation distance. It is the separation distance from any kind of danger or disturbance and birds cross this distance before incubating their eggs. This is an competitive advantage with that of other members of the species as the bird will able to give birth to new ones and its population will increase in number, so the chances of reproduction and survival increases in this case.

Question:
Chromosomes are distributed randomly during anaphase I. What are the possible chromosome combinations in the two daughter cells? (Use the following abbreviations for the chromosomes. Dark green -> DG; Light green -> LG; Dark purple-> DP, Light purple -> LP)
How does the random lining up of the homologous chromosome in Metaphase 1 contribute to Genetic Variation?
Answer:
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LPThe random arrangement of tetrads is different in every cell going through the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is different and depends on the chromosomes that form that cell.
Explanation:
1) During meiosis, organisms can produce at least four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations in the two daughter cells of the exposed example are
LG,LP + DG,DP LG,DP + DG,LP2) Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LP
The random arrangement of tetrads is different in every cell browsing the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it.
Anaphase I
Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the amount of variations in each cell is different and depends on the chromosomes that form that cell.
During meiosis, organisms can produce a minimum of four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations within the two daughter cells of the exposed example are-
LG,LP + DG,DP LG,DP + DG,LP
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
Metaphase I
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles.
The random arrangement of tetrads is different in every cell browsing the meiosis process. There is no equal alinement between the two cells.
When tetrads aline within the equatorial plane, there's no predetermined order for every one of the homologous chromosomes of every tetrad to face one among the poles then migrate to it while separating.
Any chromosome of the homologous pair might face any of the poles then migrate thereto. Each of the chromosomes has two possibilities for orientation at the plane.
When the new haploid cells are formed, the amount of variations in each cell is additionally different and depends on the chromosomes that form that cell.
This random order within the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get an equivalent genetic charge.
Therefore,the combinations of two daughter cells LG,LP + DG,DP and LG,DP + DG,LP.

Human p53 is a tumor-suppressor gene located on chromosome 17. The function of this gene is to prevent cells with damaged DNA from undergoing mitosis. What would most likely result if there were a mutation that decreased the function of the p53 gene?
The answer is “Germs cells would undergo only one meiotic division.
Explanation:
I remember learning this in my biology class
Single amino acid changes in p53 caused by TP53 gene mutations make the protein less functional. Without p53, cell proliferation is not efficiently controlled, and DNA damage can build up in cells.
How p53 gene is important?Such cells might continue to divide uncontrollably, which would promote the development of tumors. By stopping the cell cycle to give the repair mechanisms time to restore genomic stability, p53 plays a significant function as a DNA repair facilitator.
Additionally, p53 adopted a variety of roles to directly influence the operation of different DNA-repair mechanisms.
Cancer cells may develop and spread throughout the body as a result of mutations (changes) in the p53 gene.
Therefore, numerous cancer kinds and the genetic disorder Li-Fraumeni syndrome have both been linked to these alterations.

Explain how the geologic time scale is used to organize Earth’s history.
Think about how the geologic time scale was created and how it is divided. Then answer the following questions.
How did scientists from the geologic time scale?
How is this scale organized?
What processes changed the Earth's environment during Precambrian time?
Answer:
The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.
Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.
The first principle you need to understand about geologic time is that the laws of nature are always the same.
What is the Time scale?Water, for instance, freezes at 0°C. This rule has held and will continue to hold forever.
Understanding natural principles facilitate historical thinking because it provides hints about how things were very long ago. It implies that we can interpret the past using current methods.
The rock must have formed close to the sea because this law has never changed.
Therefore, The first principle you need to understand about geologic time is that the laws of nature are always the same.
