Complete dominance is when the presence of one allele ensures that the trait of the other allele is not displayed.
For example, if B codes for black fur and b codes for white fur, a rabbit with Bb will have black fur. This is because the B shows complete dominance over the b - meaning that black fur will result.
If this was incomplete dominance, a rabbit with Bb would have a mix - so grey fur.
If it was codominance, a rabbit with Bb would have black and white patches, dots or splotches.

Complete dominance
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
Complete dominance occurs when one allele completely masks the effect of another allele at the same gene locus. An example of this is the inheritance of flower color in pea plants, where the allele for purple flowers (P) is completely dominant over the allele for white flowers (p). In this case, both homozygous (PP) and heterozygous (Pp) plants will exhibit purple flowers, while only homozygous recessive (pp) plants will show white flowers. This clear masking of one allele by another is a hallmark of complete dominance.

I completed the test yesterday.------------------------------------------------------------------------------------------------------------------Scotland demonstrated their complete dominance over their opponents by winning the match five goals to nil.
The three types of dominance are complete dominance, incomplete dominance, and codominance. In complete dominance, one allele is fully expressed over another. In incomplete dominance, neither allele is completely dominant, resulting in a blending of traits. In codominance, both alleles are expressed equally, leading to a distinct phenotype that shows features of both alleles.
Total dominance of one allele means that the phenotype associated with that allele is expressed in the heterozygous condition, masking the phenotype of the other allele. This is also known as complete dominance.

Two
Complete Dominance: Where in the dominant gene completely masks the effect of the resesive gen in heterozygous conditions. Ex. Tt or Rr. Incomplete Dominance: When 2 or more alleles influence a phenotype. Ex. Flowers. Codominance: When both alleles for a gene are expressed in heterozygous offspring. Ex. Bloodtype.
