Questions and Answers

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?

    "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?

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