Recessive - In this model we use an Albino as the recessive example.
It can be applied to all recessive morphs.

Homozygous - means a pair of identical genes. These may be two identical normal genes or two identical mutant genes.

Heterozygous - means a pair of non-identical alleles. Alleles are different versions of the same gene. The usual case is a normal allele paired with a changed (mutant) allele. An individual that is heterozygous for a recessive mutant gene look normal.

Hover mouse over pairings to get results*

Heterozygous X Normal (resulting offspring are considered 50% possible hets)
Heterozygous X Heterozygous (normal looking offspring are considered 66% possible hets)
Homozygous X Normal (all offspring are hets)
Homozygous X Heterozygous
Homozygous X Homozygous
