Question

in a group of deer mice, some individuals have a hairy body and others have a hairless body. in this group, the gene for the body hair trait has two alleles. the allele b is for a hairy body, and the allele b is for a hairless body. sorbet is a deer mouse from this group. sorbets phenotype for the body hair trait is a hairy body. sorbets genotype for the body hair gene is bb. based on this information, complete the following statement. sorbet is __________ for the body hair gene. homozygous heterozygous

Explanation:

Homozygous organisms have two identical alleles for a gene, while heterozygous organisms have two different alleles. Since Sorbet's genotype for the body - hair gene is $Bb$ (two different alleles), it is heterozygous.

Answer:

heterozygous
