In alligators, the allele M results in a pigmented color, while the allele m results in a white (albino) color. Suppose that the heterozygote Mm has a pigmented color, and the homozygote mm is albino. In this case, the allele M shows with regard to the allele m.

Complete dominance

Explanation: complete dominance occur when a dominant allele in heterozygous form completely mask the effect of the recessive allele.

For example a situation where Tt having two allele and allele T for tallness is dominant over t for shortness making the plant phenotype a Tall plant. This is called complete dominance.

A condition when the heterozygous allele do not completely expressed itself over the recessive allele is called Incomplete dominance.

For the plant to have a pigmented color in an heterozygous form the allen M for pigment is completely dominant over allele m for albino.
