What term is used to describe males for X-linked genes?

Diploid

Hemizygous (correct)

Heterozygous

Homozygous

If the gene in the text were on an autosome instead of a sex chromosome, what eye color would all the offspring have?

Purple-eyed

Blue-eyed

Red-eyed (correct)

White-eyed

In the Punnett square analysis mentioned, what eye color do all the female offspring have?

Blue

Green

Red (correct)

White

Why are all the male offspring in the Punnett square analysis hemizygous recessive for eye color?

Because they received a recessive w allele from their mother. Signup and view all the answers

In X-linked genes, why do all the male offspring have white eyes in this scenario?

"All of the male offspring acquire a recessive w allele from the mother and a Y chromosome from the father." How does this influence their eye color?

They express white eyes due to being hemizygous recessive. Signup and view all the answers
