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?

Which of the following genotype(s) must a female child have in order to be color blind?
XNXN XNXn XnXn XNY XnY
(XN represents the normal color vision allele. Xn represents the color-blindness allele. Y represents the Y chromosome, which does not carry the color-vision gene.)
Which of the following genotype(s) must a color-blind male have? Explain your rationale.
XNXN XNXn XnXn XNY XnY
(XN represents the normal color vision allele. Xn represents the color-blindness allele. Y represents the Y chromosome, which does not carry the color-vision gene.)
A man is homozygous dominant for fair skin and heterozygous for black-straight hair, his wife has brown skin and black-curly hair. The wife's hair color is the same genotypically with the husband. His mother in-law hair color is red since birth. The couple wanted to have kids. Is there a possibility that their child will have brown skin, curly-red hair, Yes or NO? If yes, what is its probability?

- Red-green color blindness is an X-linked recessive disorder. If Allison is heterozygous (a carrier), and her husband, Michael, is NOT colorblind. What is the chance that their female children will be colorblind? (Note: you are calculating the probability for their FEMALE children only, in other words if they have 1 female child, what is the probability that she will be born colorblind?) 0% 25% or 1/4 50% or 2/4 75% or 3/4 100% or 4/4arrow_forwardRed-green color blindness is an X-linked recessive disorder.

- In humans, the alleles for unattached earlobes is dominant over the allele for attached earlobes. The allele for dark hair dominates the allele for light hair. If both parents are heterozygous for earlobe attachment and hair color, what types of offspring can they produce, and what is the probability for each type?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_forwardSuppose the mating had occurred between homozygous recessive male for a disease and a normal female known to be heterozygous. What would the probabilities be for the following outcomes? 3 offspring in the following order: normal, with disease, normal Use the factorial equation n!/x!(n-y)! * (p)x (q)n-x n = number of events (offspring) x = number of normal / dominant offspring n-y =total - number of abnormal / recessive offspring p = probability of producing a normal/dom q = probability of producing an abnormal/recarrow_forward
- A. Tongue rolling (T) is dominant over non-tongue rolling (t). Right handedness (R) is dominant over left (r). A non-tongue rolling, left-handed woman marries a tongue rolling, right-handed man who is heterozygous for both traits. What are the possible genotypes and phenotypes of the offspring? B. A tongue rolling, right-handed man marries a non-tongue rolling, right-handed woman. Their first child is non-tongue rolling and left- handed. What are the genotypes of the parents? Mom: Dad: C. A non-tongue rolling, right-handed man whose mother was left-handed marries a tongue rolling, right- handed woman whose mother was non-tongue rolling and left- handed. What are the possible genotypes and phenotypes of their children? D. In man, a certain type of deaf mutism is recessive. Let (D) be normal and (d) be deaf-mute. A normal, right-handed man married a normal, right-handed woman. They had a child who was a left-handed deaf-mute. What were the genotypes of the parents?…arrow_forwardIn humans, curly hair is dominant to straight hair. A woman heterozygous for curly hair marries a man with straight hair and they have children. What is the probability that the first child will have curly hair? What is the probability that in a family of four children 3 will be curly and 1 will be straight haired? What is the probability that the first three children will be curly-haired girls and the next will be a straight haired boy?arrow_forwardRed-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___arrow_forward
