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.
sugar, a deer mouse from this group, has a hairless body. sugar has two alleles for a hairless body.
based on this information, click the blue words to correct any errors in the text.
sugars genotype for the body hair gene is bb.
sugars genotype for the body hair trait is a hairy body.
sugar is homozygous for the body hair gene.

Explanation:

• Genotype refers to the genetic makeup (alleles), while phenotype is the physical trait (hairy or hairless body). So "Sugar's genotype for the body hair trait is a hairy body" is wrong as genotype is alleles (like \(bb\)) not the physical trait.
• Since Sugar has two alleles for a hairless body (\(bb\)), it is homozygous (two of the same alleles) for the body hair gene, so no error there. And "Sugar's genotype for the body hair gene is \(bb\)" is correct as per the given information (\(b\) is hairless allele and two \(b\) alleles).

Answer:

Click on "Sugar's genotype for the body hair trait is a hairy body" to correct it. (Change it to something like "Sugar's phenotype for the body hair trait is a hairless body" as genotype is \(bb\) and phenotype is the physical appearance - hairless body here).
