Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for
Bond [772]

Answer:

Hair length: hh

Hair color: Bb

Hair Texture: RR

Explanation:

In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.

The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from <em>homzygous.</em>

The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous <em>dominant</em>, which means there will be two of the same dominant alleles, so, RR.
