Complete dominance is where a dominant allele completely masks the presence of the recessive allele. An example of this can be shown in the cross below:
Azazel is a red skinned Homo-Superior homozygous with the u gene coding for red skin.
Raven is a blue skinned Homo-Superior homozygous with the U gene coding for blue skin.
| u | u | |
| U | Uu | Uu |
| U | Uu | Uu |
As shown by the cross, all the offspring should have a Uu genotype for skin colour. However, as the U allele is completely dominant over the u allele, their child Kurt expresses a phenotype with completely blue skin.
