In humans, the allele for brown eyes is dominant to the allele for blue eyes. If a man with blue eyes and a woman with brown eyes who is homozygous for eye color have children, what is the probability of having a child with blue eyes?

25 percent
100 percent
50 percent

it would be 0% because blue eyes are not dominant so all the children would be hetro brown

There is a zero percent probability of having a child with blue eyes.

The phenomenon applied here is the dominance of alleles.

What is the dominance of alleles?

  • The relationship between two variants of a gene is described as dominant.
  • Every gene has two different variations, or alleles, that an individual inherits from each parent.
  • One allele will be expressed when there are different alleles of a gene; this allele is dominant.
  • The allele whose effect has been masked by the dominant allele is known as the recessive allele.
  • In the given question allele for the brown eye is dominant over the allele for the blue eye.
  • Both the parents have homozygous alleles.
  • When each allele is transmitted from each parent to the offspring, the dominant allele masks the effect of the recessive allele, and hence the offspring produced has brown eyes because its alleles are dominant over the blue eyes.
