Answer 2

When a hybrid black guinea pig is crossed with pure a white guineapig the offspring then the resultant offspring is 1:2:1.

Explanation:

The first filial generation results in 1:2:1. One heterozygous species is obtained and 2 homozygous species are obtained. This is based on a genetic principle. This is the result of the parent allele.

There are two such hybrid variety is obtained from the experiment. Hence the production is based on ratio 1:2:1.
