What do variations of traits have to do with mutations? give an example
Answers
Genetic variations can arise from gene mutations or from genetic recombination (a normal process in which genetic material is rearranged as a cell is getting ready to divide). These variations often alter gene activity or protein function, which can introduce different traits in an organism.

In tomatoes, a heterozygous plant with normal fruit and purple stems is crossed with a recessive plant having fasciated fruit and green stems. The following distribution of offspring is observed:
normal fruit, purple stems 38.5% fasciated fruit, green stems 38.5%
normal fruit, green stems 11.5%
fasciated fruit, purple stems 11.5%
What conclusion can be made regarding the loci for fruit shape and stem color? HINT determine the RF
What the loci and RF here mean? How to answer this question?
Answers
Answer:
Recombination frequency, P = 0.23.
If the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked.
1% of recombinations = 1 map unit23% = 23 map unitsThe genes for stem color and fruit type seem to be in the same chromosome, linked and 23 MP apart.
Explanation:
In the present example, the genes for stem color and fruit type seem to be linked.
To know if two genes are linked, we must observe the progeny distribution. If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent.
In this way, we might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with lower frequencies in the progeny.
The following distribution of offspring is observed:
normal fruit, purple stems 38.5% fasciated fruit green stems 38.5% normal fruit, green stems 11.5% fasciated fruit, purple stems 11.5%38.5% + 38.5% + 11.5% + 11.5% = 100%
N (total number of individuals in the progeny) = 100
number of individuals with normal fruit, purple stems 38.5 number of individuals with fasciated fruit green stems 38.5 number of individuals with normal fruit, green stems 11.5 number of individuals with fasciated fruit, purple stems 11.5To calculate the recombination frequency we will make use of the next formula: P = Recombinant number / Total of individuals. The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU).
P = Recombinant number / Total of individuals.
P = 11.5 + 11.5 / 100
P = 0.23
We need to know that 1% of recombinations = 1 map unit = 1cm. Also, the maximum recombination frequency is always 50%. This means that if the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked. FR 23% = 23 UM.

Please help I’ll give brainliest to whoever’s right
Answers
Answer:
1:Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the only force acting on the object is gravity
2:Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
3:A scientific theory is an explanation of something in the natural world that is based on past observations and evidence.
4:In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.

When plants die this causes what to increase?
Answers
Answer:
Explanation:
Improper watering is often the reason for sudden dying of plants. If you forgot to water for a few days, it's possible that the roots dried up. ... Root rot, a result of wet, poorly drained soil, can be occurring under the surface of the soil, even if the plant looks healthy.
You have been given three plants: Two have solid black flowers, and one has grey flowers. You cross each black-flowered plant to the grey plant with the following results:
Parents: black #1 X grey F1: 87 solid black, 83 spotted black
Parents: black #2 X grey F1: all black
To try and make sense of these results, you intercross the solid black-flowered F1 plants from cross #2 with the following results in the F2:
132 black
35 spotted black
11 grey
What are the genotypes of the parents, F1 and F2 generations?
Answers
Answer:
The correct answer would be -
F1: #1 black flower plant = Aabb and aabb and #2 = AABB and aabb
F2 = AaBb and AaBb

What is your opinion on the use of stem cells, obtained from fertilized eggs or early stage embryos
Answers
USE OF STEM CELL:
The first attempts to turn mature cells back into pluripotent stem cells involved a process called cloning. In the cloning process, an egg is fertilized in the lab, and right after fertilization, the DNA is removed from the egg.These stem cells come from embryos that are three to five days old. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.Learn more:

A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh-positive is a trait that shows simple dominance over Rh-negative. Which of the following is a possible phenotype for the father?
A) A negative
B) O negative
C) B positive
D) AB negative
Answers
Answer:
The correct answer is - C) B positive
Explanation:
In the given question is the man has B positive blood group with two offspring a girl with type O positive and a son who is type B negative. In ABO blood group A and B if present together they express in offspring if present together.
Here the difference in the Rh factor only as the blood group O has no antigen on its surface therefore the most possible phenotype for the father as he has son with B negative and a daughter with O positive.
