Question

1. In guinea pigs, long hair is dominant to short hair. A pure bred short haired guinea pig is bred with a hybrid

long haired. What does each of those look like? (use the letter H)

Pure bred (homozygous)______?

Answer 1

When a purebred short-haired guinea pig (hh) is bred with a hybrid long-haired guinea pig (Hh), all the offspring will have long hair (Hh).

Step-by-step explanation:

In guinea pigs, long hair is dominant to short hair. When a purebred short-haired guinea pig (homozygous for short hair, represented by the genotype hh) is bred with a hybrid long-haired guinea pig (represented by the genotype Hh), the offspring will all have long hair.

This is because the dominant allele for long hair (H) is present in the hybrid guinea pig and can be passed on to all its offspring.

So, the phenotype of the purebred short-haired guinea pig is short hair (hh), while the phenotype of the hybrid long-haired guinea pig is long hair (Hh).

Answer 2

A short haired pure bred would be hh.

Pure bred long haired would he HH.

A hybrid would be Hh.


I put all of the options for them just in case :)
