X-linked Recessive Traits Review X-linked traits in your textbook. 1 In cars, the Ballele produces black fur & b produces orange fur. This gene is X-linked (X & X". Both colors are expressed in heterozygotes calico). If alcat has 2 calico kittens, 1 male black kitten, and I female orange kitten, what is the ty p henotype of the father cat? (Hint: Work backwards & use a Punnett square Remember that not every type of offspring must be born, and more than one of the same type may be born, due to chance.) b Genotype: mother : father cPhenotype: mother calico father d You see a calico car. Is it male or female? How do you know? 2 Redureen color deficiency is an X-linked recessive trait in humans. Suppose a color deficient woman marries a man with normal color vision. Using a Punnett square, show why all of their sons will be color deficient, and all of their daughters will have normal vision. a Genotypes: Xxx Xvy. Gametes: Mother: Father: O C Punnett square: b Why is there no superscript N on the father's Y chromosome? Can this female pass along a normal allele to her offspring? Why or why not? 3 The most common form of hemophilia (inability to clot blood) in humans is an X-linked recessive disorder. Albinism is an autosomal recessive disorder. A normal male marries a normal woman. The man's father had albinism (as), but no one in his family had hemophilia. The woman's mother had albinism (ad) and her father had hemophilia (XⓇY). Albinism is autosomal recessive, and hemophilia is X-linked recessive.
