If the allele for brown eyes is dominant and the allele for blue eyes is recessive, which genotype produces a person with blue eyes?
A) A blue-eyed person is homozygous with two alleles for brown eyes.
B) A blue-eyed person is homozygous with two alleles for blue eyes.
C) A blue-eyed person is heterozygous with one allele for blue eyes and one allele for brown eyes.
D) The alleles for eye color are demonstrating codominance.

Quizplus · Accepted Answer

In order for a person to have blue eyes, they must inherit two recessive alleles for eye color. Therefore, the genotype of a person with blue eyes is homozygous recessive, which is represented as bb. Choice A would produce a brown-eyed person because homozygous dominant individuals have two alleles for brown eyes. Choice C would produce a brown-eyed person with the genotype of heterozygous, which is represented as Bb. Choice D is incorrect because there is no mention of codominance in the scenario.
