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 child (boy or girl)?

#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?

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...

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,...

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...

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...

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...

Hemophilia is a sex-linked trait. A hemophilic man, whose father was normal, marries a woman whose father had hemophilia and whose mother was heterozygous for hemophilia. What are the chances that their son will have hemophilia? A daughter will have hemophilia? (Since there are two possibilities for the mother, you must use the data from two Punnett Squares to answer these questions.) Mr. X has been accused by Miss Z of fathering her child. The child's blood type is AB...

4. In humans, red-green color blindness is recessive to normal sight. The gene for this trait is carried on the X chromosome. In each of the following, give the genotype and phenotype of all possible offspring and their expected ratios. Give the phenotypic ratios of males ♂ and females ♀ separately (ALWAYS FOR X-LINKAGE): (a) a color-blind man married to a normal- sighted woman whose father is color-blind; (b) a man with normal color vision married to a color-blind woman.
