Is albinism an example of epistasis

Web14 okt. 2024 · Is albinism an example of epistasis? A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene. The gene for albinism (lack of pigment) in humans is an epistatic gene. How does epistasis affect selection? Conclusions. WebAlbinism is a group of inherited disorders that results in little or no production of the pigment melanin, which determines the color of the skin, hair and eyes. Melanin also plays a role in the development of certain optical nerves, so all forms of Albinism cause problems with the development and function of the eyes.

WebExample of Epistasis - Dominant and Recessive Epistasis It is the phenomenon by which one gene does not allow alleles of another locus to express. This is a counterpart of dominance.
