13. How do babies get their homologous pairs of chromosomes, if an egg and sperm are only haploid (23
chromosomes)?
Answer:
When a sperm fertilizes an egg, the resulting fertilized egg, or zygote, has a complete set of homologous pairs of chromosomes, with one set inherited from the mother's egg and one set inherited from the father's sperm. This happens because the egg and sperm each contain only one copy of each chromosome, rather than the full set of two copies that are found in the cells of the body. When the egg and sperm fuse, the resulting zygote has a full complement of chromosomes, with one copy of each chromosome from each parent.
Answer:
When a sperm and egg join during fertilization, the egg and sperm contribute their haploid set of chromosomes to form a diploid zygote. The haploid sets of chromosomes pair to form homologous pairs, with one chromosome in the team coming from the mother and the other from the father.

Genes A and B are farther apart than genes A and C, and all three genes are linked. Which of the following conclusions could be drawn from this information? CHOOSE ALL THAT APPLY Gene Cmight be between genes A and B. Gene B might be between genes A and C. Gene A might be between genes B and C. More crossovers will occur between genes A and C than between A and B More crossovers will occur between genes A and B than between genes A and C.
The following conclusions could be drawn from this information:
a) Gene C might be between genes A and B.
c) Gene A might be between genes C and B.
e) More crossovers will occur between genes A and B than between genes A and C
When two genes are located closer to each other on a chromosome and are passed down as a single unit. Then, those genes are referred to as linked genes. Genes are considered linked if their recombination frequency is less than 50%.
Given that the A and B genes are further apart than the C and A genes, the sequence could consist of A, C, and B genes. Option E is correct; the C gene may be situated between the A and B genes.
it is possible that A and B genes are further apart than A and C genes, indicating that A and B genes are further apart than A and C genes. Crossovers are more likely to occur between genes that are further apart. Because the distance between the A and B genes and the C genes is greater, there will be more crossover between the A and B genes than there is between the C and A genes. B is incorrect, whereas A is correct.

a. What type of cross did Mendel perform which lead to his "traits don't blend" discovery?
Answer:
He crossed pure bred green seeded and pure bred yellow seeded plants.
Explanation:
Recently had this on one of my quizzes :)
Mendel crossed pure bred green seeded and pure bred yellow seeded plants.
What was Mendel's law?Mendel's first law is the law of segregation in which during gamete formation each member of a gamete pair separates from the other member to form the genetic constitution of the gamete.
The second law of Mendel is the law of independent assortment which describes how alleles of different genes independently segregate from each other during the formation of gametes.
Mendel's third law was the law of inheritance which states that the separation of an allele pair into two daughter cells during the second phase of meiosis does not affect the way in which the other allele pair separates or segregates.
Mendel's laws are important because they allow us to understand how characters are inherited and what determines the phenotypes that are obtained by different individuals. When Mendel crossed pure bred green seeded and pure bred yellow seeded plants, these traits don't blend during his discovery.
Thus, Mendel crossed pure bred green seeded and pure bred yellow seeded plants.

Frank has Klinefelter syndrome (47,XXY) His mother has normal skin, but his father has anhidrotic ectodermal dysplasia; X-linked condition where the skin does not contain sweat glands. Frank has patches of normal skin and patches of skin without sweat glands_ Complete the sentences_ Some answers may be used more than once Or not at all:
Frank received the mutant chromosome from his father. Nondisjunction occurred in his father during the father meiotic division.
Hyperhidrotic ectodermal dysplasia is indeed a genetic disorder caused by mutations in one or more genes. EDA, EDAR, EDARADD, as well as WNT10A are examples. The most major reason of the disorder is EDA gene mutations, which make up more than half of any and all cases.
Nondisjunction would have happened during meiosis I. Because at that point, the chromosomes (rather than chromatids) separate. Both XY chromatids would've have gone into the a single cell during separation. So, during meiosis II, when XY chromosome sperm fuses with X chromosome egg, the daughter cell will have a XXY genotype, which really is klinefelter syndrome.

PLEASE HELP! Why is it possible that the oxygen and carbon dioxide on earth will never be used up in regard to photosynthesis and respiration?
Answer:
This is because the process of photosynthesis and respiration is a cycle, meaning that the oxygen and carbon dioxide are constantly being exchanged and reused. Oxygen is produced from photosynthesis, and carbon dioxide is produced from respiration. This cycle is self-sustaining, so the oxygen and carbon dioxide on Earth will never be completely used up.

What are two things which the Sun sends out into the Solar System which have negative effects and what are those effects ? How does solar activity change over time?
Answer:
The Sun sends out two types of particles that can have negative effects in the Solar System: solar wind and solar flares. Solar wind is a stream of charged particles that is constantly emitted from the Sun's atmosphere. These particles can affect the orbits of planets and other objects in the Solar System, and can also interfere with satellite and radio communications on Earth. Solar flares are intense bursts of radiation that are emitted from the Sun's surface. They can cause disruptions to satellite and radio communications, and can also pose a danger to astronauts and other people in space.
Solar activity, including the emission of solar wind and solar flares, varies over time. The Sun follows an approximately 11-year cycle of activity, during which the number of sunspots and other indicators of solar activity rise and fall. At the peak of the cycle, the Sun is more active and is more likely to produce solar flares and other forms of solar activity. At the low point of the cycle, solar activity is lower and the Sun is less likely to produce these effects.
