Question

in a group of guinea pigs, some individuals have brown eyes and others have red eyes. in this group, the gene for the eye color trait has two alleles. the allele for brown eyes (e) is dominant over the allele for red eyes (e).
the punnett square below shows a cross between two guinea pigs. consider the phenotypes of the offspring shown. select one box that represents offspring with red eyes.

Explanation:

In genetics, the allele for brown eyes \(E\) is dominant over the allele for red eyes \(e\). A dominant allele masks the expression of a recessive allele. For an organism to show the recessive trait (red eyes in this case), it must have two copies of the recessive allele. Looking at the Punnett square, the genotype \(ee\) represents two recessive alleles.

Answer:

The boxes with the genotype \(ee\) (the two bottom - right and bottom - left boxes in the Punnett square) represent offspring with red eyes.
