Question

this passage describes the ear type trait in rats:
some rats have dumbo ears, which are larger and rounder than normal ears. dumbo ears are also set on the sides of the rats head instead of on the top. the word dumbo comes from the name of a cartoon elephant whose ears had a similar appearance.
in a group of rats, some individuals have normal ears and others have dumbo ears. in this group, the gene for the ear type trait has two alleles. the allele e is for normal ears, and the allele e is for dumbo ears.
jellybean, a rat from this group, has dumbo ears. jellybean has two alleles for dumbo ears.
based on this information, click the blue words to correct any errors in the text.
jellybeans phenotype for the ear type trait is normal ears.
jellybeans phenotype for the ear type gene is ee.
jellybean is heterozygous for the ear type gene.

Explanation:

First Sentence Correction:

Jellybean has dumbo ears (given), so the phenotype for ear type trait should be dumbo ears, not normal ears. We correct "normal ears" to "dumbo ears".

The term "phenotype" refers to the observable trait (dumbo ears here), while "genotype" refers to the genetic makeup (alleles, like ee). So we need to change "phenotype" to "genotype" as ee is the genetic composition.

Jellybean has two alleles for dumbo ears (ee), meaning it has two identical alleles (homozygous), not heterozygous (which would be different alleles, like Ee). So we change "heterozygous" to "homozygous".

Answer:

Jellybean's phenotype for the ear type trait is dumbo ears.
