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 e is for brown eyes, and the allele e is for red eyes.
penny, a guinea pig from this group, has brown eyes. penny has one allele for brown eyes and one allele for red eyes.
based on this information, click the blue words to correct any errors in the text.
pennys genotype for the eye color trait is red eyes.
pennys genotype for the eye color gene is ee.
penny is homozygous for the eye color gene.

Explanation:

1. Genotype refers to the genetic makeup. Since Penny has one allele for brown eyes ($E$) and one for red eyes ($e$), her genotype is $Ee$, not "red eyes" which is a phenotype.
2. Having the genotype $Ee$ is correct as per the description.
3. Homozygous means having two identical alleles. Since Penny has $E$ and $e$ (different alleles), she is heterozygous, not homozygous.

Answer:

1. Change "red eyes" to "Ee".
2. No change needed.
3. Change "homozygous" to "heterozygous".
