-
When gametes are formed, the two alleles of each gene are separated

Punnet Squares
A Punnett square is a chart that allows you to easily determine the expected percentage of different genotypes in the offspring of two parents
a dihybrid cross, both parents are heterozygous for pod color (Gg) and pod form (Ff).

In a testcross, an organism with an unknown genotype but dominant phenotype is crossed with an organism that is homozygous recessive for the same trait.
