Chapter 3, Problem 12P
A woman’s father has ornithine transcarbamylase deficiency (OTD), an X-linked recessive disorder producing mental deterioration if not properly treated. The woman’s mother is homozygous for the wild-type allele.
a. What is the woman’s genotype? (Use D to represent the dominant allele and d to represent the recessive allele.)
b. If the woman has a son with a man who does not have OTD, what is the chance the son will have OTD?
c. If the woman has a daughter with a man who does not have OTD, what is the chance the daughter will be a heterozygous carrier of OTD? What is the chance the daughter will have OTD?
d. Identify a male with whom the woman could produce a daughter with OTD.
e. For the instance you identified in part (d), what proportion of daughters produced by the woman and the man are expected to have OTD? What proportion of sons of the woman and the man are expected to have OTD?

A couple who are about to get married learn from studying their family histories that, in both their families, theirunaffected grandparents had siblings with cystic fibrosis(a rare autosomal recessive disease).a. If the couple marries and has a child, what is theprobability that the child will have cystic fibrosis?b. If they have four children, what is the chance that thechildren will have the precise Mendelian ratio of 3:1 fornormal:cystic fibrosis?c. If their first child has cystic fibrosis, what is theprobability that their next three children will be normal?
A man who has color blindness and type O blood has children with a woman who has normal color vision and type AB blood. The woman’s father had color blindness. Color blindness is determined by an X-linked gene, and blood type is determined by an autosomal gene.
a. What are the genotypes of the man and the woman?
b. What proportion of their children will have color blindness and type B blood?
c. What proportion of their children will have color blindness and type A blood?
d. What proportion of their children will be color blind and have type AB blood?
Color-blindness is an X-linked, recessive trait. If a normal-sighted woman, whose father was color-blind, marries a color-blind man, what is the probability that they will have a son who is color-blind? (use the letter “B”)

- I will be adding two questions here because I asked two of the same questions twice by accident earlier. A man and a woman do not have hemophilioa, but the womans father did. (Hemophilia is X-linked recessive). a) What is the probability that they will have a child with hemophilia? b) Is it possible for any of their daughters to be affected? Explain. A cross between a horse homozygous for red hair and a horse homozygous for white hair results in offspring with the coat colour called roan. When you look at the fur of the roan offspring you see both red and white hairs. What type of inheritance best explains this? a) blending inheritance b)codominance c)incomplete codominance d)multiple allelesarrow_forwardA woman with type A blood and a man with type B blood have a child with type O blood. Can this man be the father? Choose the best answer below: a No, he can not be the father because A and B are codominant b No, he cannot be the father because type O blood is recessive c Yes, he can be the father if both parents are carriers for type O blood d Yes, he can be the father if the blood type is X-linked on the maternal sidearrow_forwardA mother is heterozygous for the X-linked gene for colorblindness and also heterozygous for the autosomal inherited sickle cell anemia. She is married to a man who can see color normally and who is heterozygous for sickle cell trait. Using b (colorblind), B (normal color), S (normal hemoglobin), s (sickle cell), answer the following: a. What are the genotypes of the parents? b: What is the probability of having a child who is both color blind and has sickle cell anemia?arrow_forward

List the genetypes of the mom, man, and baby. Can the woman prove he is the father or can he is not? Why or why not? If the accused man was type A insyead of type AB, what would be his possible genotypes? Could the woman prove he is the father? Can the man prove he is not the father? Why or why not?arrow_forwardMuffy, a color blind female with blood type A (heterozygous to type O) is married to Biff, who is also color blind and is homozygous for type B blood. Muffy has been having an affair with their gardener, Raoul, who is heterozygous for type B blood and has normal vision. Recall that color blindness is a sex linked recessive condition.

- In a disputed parentage case, the child is blood type O, while the mother is blood type A. What blood type would exclude a male from being the father?

Give the genotypes of both the mother and of the daughter. b) The mother claims a man who is type B is the father. Is that possible? Explain. c) The accused man can prove that both of his parents are type AB. Is it possible for him to be type B?

If a mother is a carrier, what percentage of her sons will have the trait? Please give me example of sex linked recessive trait.arrow_forward
