People have been interbreeding plants for particular traits since we first started farming more than 11,000 years ago. The science of genetics began with plants. When paired with a red allele, the cream allele produces horses with golden coats such as palominos and buckskins. The cream gene in horses is a classic incomplete dominant.The result is an intermediate inheritance: the wavy-haired labradoodle. Just like humans, that comes from having straight-haired and curly-haired parents. On the subject of dogs, lots of labradoodles have wavy hair.Pups of long-tailed and short-tailed parents often split the difference and have medium-length tails. Tail length in dogs is often determined by incomplete dominance.That's a classic example of incomplete dominance producing a trait different from either of the parents. When a long-furred Angora rabbit and a short-furred Rex rabbit reproduce, the result can be a rabbit with fur longer than a Rex, but shorter than an Angora.When a black and a white chicken reproduce and neither allele is completely dominant, the result is a blue-feathered bird. Chickens with blue feathers are an example of incomplete dominance.Here are several examples of the effects of incomplete dominance in animals: Incomplete dominance in animals is most widely studied in domestic animals since it's important for their health, appearance, and value.
