When one parent with straight hair and one with curly hair have a child with wavy hair, that's an example of incomplete dominance.Д®ye color is often cited as an example of incomplete dominance.However, one or both of their parents may have been carriers who had incompletely dominant genes, causing them to produce one half of the necessary enzyme, which is enough for a normal life. This neurological disease is caused by an enzyme imbalance and is autosomal recessive that is, people who actually suffer from the disease have two recessive genes that cause it. Tay-Sachs Disease is an example of incomplete dominance in humans.

The incomplete dominance causes the generation of cells that do not have enough receptors to remove all dangerous cholesterol from the bloodstream. One allele causes liver cells to be generated without cholesterol receptors, while another causes them to be generated normally.

The disease familial hypercholesterolemia (FH) is an example of incomplete dominance.

Incomplete dominance is just part of what makes our species so complicated and interesting. Incomplete dominance is rare in humans we're genetically complex and most of our traits come from multiple genes. Just compare the original plant, teosinte, with a modern ear of corn to see the genetic difference! Corn with multiple incompletely dominant traits is generally healthier and provides greater yields than 'purer' strains with fewer such traits.

Incomplete dominance is a key element of improving crops such as corn.

Combining deep purple eggplants with white eggplants results in eggplants of a light violet color. The fruit color of eggplants is another example of incomplete dominance.Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant. Pink snapdragons are a result of incomplete dominance.That 1:2:1 ratio - a quarter like one parent, a quarter like the other, and the remaining half different from either - is common in cases of incomplete dominance. However, mixing the pink flowers results in Вј red, Вј white and ВЅ pink. Those pink flowers are a result of incomplete dominance. Mixing the two results in pink flowers, just like Dr. Wild four-o-clocks tend to have red flowers, while 'pure' four-o-clocks with no coloration genes are white. Four-o-clocks are flowering plants that get their funny name from their inclination to bloom in the late afternoon.Instead, many came up pink! Kolreuter found that neither allele was fully dominant in his flowers and identified the concept of incomplete dominance. The German scientist Josef Kolreuter bred red and white carnations, expecting to get offspring with the dominant red coloration. Incomplete dominance was first recorded in plants.Whether for food, other uses, or simple beauty, humans have employed genetic selection of plants, including incomplete dominance, throughout our history. Gregor Mendel, one of the founders of genetic science, began his studies by recording the ways he planted his garden. 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.
