Pink roses are often the result of incomplete dominance. When red roses, which contain the dominant red allele, are mated with white roses (which is recessive), the offspring will be heterozygotes, and will express a pink phenotype.
Examples are:
A snapdragon flower that is pink as a result of cross-pollination between a red flower and a white flower when neither the white or the red alleles are dominant.
A brown fur coat on a rabbit as a result of one rabbit's red allele and one rabbit's white allele not dominating.
A child with wavy hair as a result of one parent's curly hair and the other's straight hair.
An Andalusian fowl produced from a black and a white parent is blue.
A carnation that is pink that is a result of cross-pollination between a red carnation and a white carnation.
A black sheep and a white sheep mate and have a grey sheep.
A black dog and a brown dog mate and the result is a dog with a brindle coat.
A white cat and a brown cat mate and the result is an orange cat.
A tall horse and short horse mate and the offspring is off medium stature.
A big American bulldog and a small American bulldog mate and their offspring is medium-sized.
A long tailed dog and a short tailed dog mate and the offspring has a medium lengthened tail.
