Gametes, Genotypes, and Phenotypes
Sometimes, it is easier to determine how many possible phenotypes, genotypes, and gametes are available from the crossing of two parents. The equations are as follows:
N is the number of heterozygous gene pairs. For instance, if a genotype is AaBbCc, n will be 3. However, if the genotype is AABbCC, the n is 1.
When analyzing two parents, it is easier to determine how many possible phenotypic and genotypic combinations of each gene pair, and then multiply them all together.
All of this can be figured if there is no linkage.
