#9 In humans red-green colorblindness is inherited in an X-linked recessive pattern. Polydactyly (extra fingers and toes) is inherited in an autosomal dominant pattern. A woman with polydactyly (heterozygous) and normal vision marries a man with red-green colorblindness and normal fingers and toes. What phenotypes would you expect to see among their children?

Expert Solution

I have written the result in two different way, you can write the answer in both or either of the two way.

#9 In humans red-green colorblindness is inherited in an X-linked recessive pattern. Polydactyly (extra fingers and toes) is inherited in an autosomal dominant pattern. A woman with polydactyly (heterozygous) and normal vision marries a man with red-green colorblindness and normal fingers and toes. What phenotypes would you expect to see among their children?

An X-linked recessive allele, r, produces red-green colorblindness in humans. A normal woman whose father was colorblind marries a colorblind man. a. What is the chance that the first child from this marriage will be a colorblind boy? b. What is the chance that the first child from this marriage will be a colorblind girl? c. If the couple have three children, what is the probability that two of them will be colorblind boys and one will be a normal...

In human beings, the gene for red green colorblindness (r) is sex linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. a. What is the genotype of the woman's father? b. What is the probability that the couple's first child will be a...

QUESTION 6 Red-Green colorblindness is a X-linked recessive disorder. Huntington’s is an autosomal dominant disorder. Susan’s father is color blind and has Huntington’s disease and is heterozygous for the Huntington’s allele. Her mother is normal and has no history of colorblindness or Huntington’s in her family. Her brother has developed Huntington’s but is not colorblind. Her husband Greg is healthy and has no incidence of either disorder in his family. Susan is not colorblind and has not yet be tested...

Red-green color blindness is due to an X-linked recessive allele in humans. A widow’s peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele. Consider the following family history: A man with a widow’s peak and normal color vision marries a color-blind woman with a straight hairline. The man’s father had a straight hairline, as did both of the woman’s parents. Use the family history to make predictions about...

A recessive allele on the X chromosome is responsible for red-green color blindness in humans. A woman with normal vision whose father is red-green color blind marries a male with normal vision. Which of the following best predicts the phenotypes of their children? A. All of the children will have normal vision. B. All of the daughters will have normal vision, and half of the sons will be red-green color blind. C. All of the daughters will have normal vision,...

1)Red-green color blindness is a sex-linked recessive trait in humans. Two people with normal color vision have a color-blind son. What are the genotypes of the parents? A)XnXn and XnY B)XNXN and XNY C)XNXn and XNY D)XNXN and XnY 2)A poison interferes with the action of RNA polymerase II, but not RNA polymerase I or III. Which of the following is likely to be true of a cell exposed to the poison? A)production of tRNA would be stopped but not...

In human’s classical hemophilia is inherited as X-linked recessive disease. Albinism (lack of pigmentation) is inherited as autosomal recessive disorder. A son with both anomalies was born to healthy parents. Which is probability that the second son in this family also will have both these disorders at the same time?

Colorblindness is an X-linked recessive trait. Let us assume that a colorblind man has a colorblind sister and his mother has normal vision. What is the genotype, as to color vision, of this man’s mother and of his father? What kind of color vision will his sons and his daughters have, and in what ratios, if he marries a woman identical in genotype to his mother?

a. Red green color blindness is a sex linked recessive trait. If a woman with normal vision whose father is colorblind marries a man with colorblindness. What would be the probability that they have a colorblind child? b. Two parents have ABO blood group genotypes. Which of the following blood types could not belong to one of their children? AB, B, O, A. c. A women who is a carrier for colorblindness marries a normal male. What is the probability...
