Red-green color blindness is an X-linked recessive trait in humans. A color-blind woman marries a man with normal vision but whose father was color-blind.
a. What are the genotypes of the parents?
b. What proportion of their offspring will be color-blind? |

If the gene for inheriting the trait, "I'm too lazy to do anything" is X - linked recessive, and a homozygote man on this topic board marries a heterozygote women. What percent of their children will be lazy f_____g b_____es?
Nevermind, 100%. |

Red-green color blindness is inherited as an X-linked recessive. How can a man with normal color vision father a daughter who is red-green color-blind? |

107. An X-linked recessive gene (c) produces red-green color blindness. A normal woman whose father was color blind marries a color-blind man. a. What are the possible genotypes for the mother of the color-blind man? b. What are the possible genotypes for the father of the color-blind man? c. What are the chances that the first son will be color blind? d. What are the chances that the first daughter will be color blind? |

a normal color female is corssed to a yellow male. In F1 1/2 females are normal color, 1/2 are yellow, 1/2 males are normal color 1/2 are yellow. Suggest two hypothesis that might explain these results? |

107. An X-linked recessive gene (c) produces red-green color blindness. A normal woman whose father was color blind marries a color-blind man. a. What are the possible genotypes for the mother of the color-blind man? b. What are the possible genotypes for the father of the color-blind man? c. What are the chances that the first son will be color blind? d. What are the chances that the first daughter will be color blind?
108. If a father and a son are both color blind and the mother is normal, is it likely that the son inherited color blindness from his father?
109. In humans, an X-linked disorder called coloboma iridia (a fissure in the iris) is a recessive trait. A normal couple has an afflicted daughter. The husband sues the wife for divorce on the grounds of infidelity. Would you find in his favor?
110. In Drosophila a narrow reduced eye is called a bar-eye. It is due to a dominant X-linked allele (B), whereas the full wild-type is due to the recessive gene (B +). Give the F1 and F2 genotypic and phenotypic expectations of a cross of a homozygous wild-type female with a bar-eyed male.
111. If the gene for yellow body color (y) is an X-linked recessive and its dominant counterpart (y+) produces wild body colors, give the phenotypes expected and their frequencies for the following four crosses: a. yellow female x wild male b. wild carrier female x wild male c. wild carrier female x yellow male d. homozygous wild female x yellow male
112. Two Drosophila are crossed several times, with a total number of offspring of 106 females and 48 males. There is too great a deviation from the expected 1:1 ratio for chance alone to account for the difference. What other factor could account for this difference?
113. White eyes in Drosophila is a mutation that turned out to be an X-linked recessive. Would you expect that the first time the white eye was discovered it was in a male or female?
114. Hemophilia is an X-linked recessive gene. A normal woman whose father had hemophilia marries a normal man. What are the chances of hemophilia in their children?
115. Color blindness is an X-linked recessive gene. Two normal-visioned parents produce a color-blind child. a. Is this child male or female? b. What are the genotypes of the parents? c. What are the chances that their next child will be a color-blind daughter?
116. Red-green color blindness is an X-linked recessive trait. Two normal-visioned parents have a color-blind son. Indicate the genotype and phenotype of each parent and the son.
117. There is an autosomal gene that controls baldness, and its expression is sex-influenced, so that the gene for baldness (B) is dominant in males but recessive in females. In females the allele B1 for nonbaldness is dominant over the gene for baldness. If a heterozygous nonbald woman marries a nonbald man, what will be the appearance of their children? Work out the possibilities for each sex.
118. Short index fingers (shorter than ring finger) are dominant in males and recessive in females, whereas long index fingers (as long as or longer than ring fingers) are dominant in females and recessive in males. Give the F2 genotype and phenotype resulting from the cross of a male with long index fingers with a female with short index fingers.
