Cat breeders are aware that kittens expressing the X-linked calico coat pattern and tortoiseshell pattern are almost invariably females. Why are they certain of this?

Predict the probability (using a Punnett square) of producing an offspring affected by a single gene X-linked mutation given the genotype of the parents. Compare these crosses in two cases: where the mutant allele is “A” vs where the mutant allele is “a” (XAXA x XaY) (XAXa x XAY) (XAXa x XaY) (XaXa x XAY) (XaXa x XaY). Include gender in the phenotype.

6) Duchenne muscular dystrophy (DMD) is a muscle wasting disease and is an X-linked recessive disorder. A man with this disease has children with a woman who does not have the disease, but her father did. If they had a ason, what would be the chance that he would have DMD? If they had a daughter? Any child? Construct a Punnett square to determine the answers. 10) In cats, coat color is completely dominant to albino (Mendelian genetics) and is an autosomal trait. Playa is a female albino cat and is crossed with Azul, a black-coated male. In their first litter, they have 4 black kittens and 2 albino kittens. If in the second litter, they have 8 kittens, how many of the kittens are expected to be albino? Construct a Punnett Square to determine the answer.

What do you think that means about the frequency of X-Linked Traits in people who arebiologically XY?

What are X-linked traits?

Can you please not type the answer can you write it on a paper

Men are more likely to display an X-linked recessive disorder than are women. Why do you think this is true?

Can the Lyon hypothesis be tested in a human female who is homozygousfor one allele of the X-linked G6PD gene? Why, or why not?

What would be the outcome of a cross between a heterozygous female and a male that carries two normal copies of the Igf2 gene?

Pedigrees indicate that color blindness and which two forms of hemophilia are X-linked traits?
