In animals, traits like milk production in cows, egg-laying in chickens, and behaviors in dogs are polygenic, indicating that multiple genes regulate these physical characteristics. What are some examples of po
Certainpolygeniccharacteristics, like skin, eye, and hair color, necessitate the existence of an epistatic gene. However, in human populations, not all polygenic traits are the outcome of epistasis. For instance, the existence of an epistatic gene is not necessary for the development of blonde, ...
Genes that control the behaviors and functionality of multiple genes that have unrelated features are calledpleiotropic genes. Sometimes it has been observed that those traits are very similar in nature while on many occasions they tend to be very non-identical with others. The problems that arise...

Polygenic traits tend to result in a distribution that resembles a bell-shaped curve, with few at the extremes and most in the middle.David Remahl/Wikimedia Commons Diversity in a population is decreased due to stabilizing selection—genotypes which are not selected are reduced and can disappear...
What are polygenic traits in biology? What characteristics do mutations have? What is adaptive divergence in evolution? Are adaptations genetic mutations? What is an example of directional selection in animals? What are examples of non-heritable traits? What adaptations did our ancestors gain t...
What is the term used to describe the heritable, physical characteristics of a living organism? In what types of organisms does meiosis occur? In what ways can DNA mutate without affecting the phenotype? What is an example of a silent mutation? What are polygenic traits in biology? What are...
Well, polygenic traits, as their name implies with the poly root, which means many, and the genic root here, which of course is referring to genes. These are going to be single phenotypic traits that are affected by multiple genes. And again, you can see that within the root polygenic....
