How do you determine the number of genotypes and phenotypes?

c. The number of different genotypes is 3 n where n = number of genes. For simple dominant–recessive relations, the number of different phenotypes is 2 n , where n = number of genes.

What percentage of offspring would have genotype?

In the cross shown above, you can see that one out of four offspring (25 percent) has the genotype PP, one out of four (25 percent) has the genotype pp, and two out of four (50 percent) have the genotype Pp. These percentages of genotypes are what you would expect in any cross between two heterozygous parents.
