Textbook Question
Chapter 12, Problem 10TYK
A man is homozygous dominant for alleles at 10 different genes that assort independently. How many genotypically different types of sperm cells can he produce? A woman is homozygous recessive for the alleles of 8 of these 10 genes, but she is heterozygous for the other 2 genes. How many genotypically different types of eggs can she produce? What hypothesis can you suggest to describe the relationship between the number of different possible gametes and the number of heterozygous and homozygous genes that are present?

- 1. If one parent is Tt, what alleles can they pass on to an offspring? (we're talking about a parent producing a gamete, right?) 2. If one parent is TT and the other parent is Tt, what are the possible offspring (These are zygotes, right?) --This is where it gets confusing so make sure to read over Larsen's explanation, and my explanation in the lecture video. The first two questions were super simple, but they were designed to orient your thinking for a dihybrid cross 3. If one parent is TtRr, what alleles can they pass on to an offspring? (what do their gametes look like in terms of letters?) 4. Same as #3, but with different letters. If one parent is TTrr, what alleles can the pass on to an offspring?arrow_forwardIn mice, there is an allele that in the heterozygous condition, produces mice with yellow coats. Mice that are homozygous recessive for the allele have white-color coats. Homozygous dominant mice abort early or are born stillborn. If a yellow male is mated to female yellow mouse, what is the phenotypic ratio you would expect among the 15 living offspring? (Show your work below.)arrow_forwardIn the USA the frequency of carriers for the devastating autosomal recessive trait of procrastination is 1/10 people. You do not procrastinate and want to have a child with another highly efficient non-procrastinator. You are worried that you both might be carriers and that your child would be a procrastinator. What is the probability that you are a carrier, AND your mate is a carrier, AND your child is procrastinator?arrow_forward

- Skin color in humans is determined by a polygenic inheritance system, possibly involving as many as 9 genes. For simplicity let’s consider the influence of 2 genes: A and B, where the dominant allele darkens skin color. Suppose a woman who is AABb mates with a man who is Aabb. List all of the possible genotypes and the consequent ratios of the gametes that could be produced by the parents.arrow_forwardIn cats, coat color is an X-linked trait with incomplete dominance. Yellow coat is caused by the allele XT and black coat by the allele Xt. A tortoise coat is caused by the heterozygous condition. What are the possible gametes that a female cat with a black coat could produce?

A colorblind man has a child with a woman who is a carrier of the disorder. Given the following genotypes: XN= normal vision and Xn = colorblindness, what is the chance of having colorblind daughters? * 100% 50% 25% 75%arrow_forward
- Black eye (B) is dominant over brown eye (b). A man that is a homozygous dominant black-eyed marries a woman that is a heterozygous black-eyed.
