WebIn horses, some of the genes for hair color are incompletely dominant. Genotypes are as follows: brown horses are BB, white horses are WW and a BW genotype creates a yellow-tannish colored horse with a white mane and tail, which is called “palomino”. WebIncomplete dominance can be seen in several types of flowers, including pink tulips, carnations and roses—any pink flowers in these are due to the mixing of red and white alleles. Incomplete dominance can also be observed in some animals, such as rabbits.
