Epistasis

Phenomenon in genetics that one gene (a pair of alleles) suppresses the operation of another gene (pair of alleles). Epistasis is a type of a non-Mendelian inheritance pattern. Epistasis comes in different types. Note: Epistasis may also occur between three or more genes, in quantitative genetics. NT: dominant epistasis ↔ recessive epistasis ↔ cumulative isomery…

Multiple alleles

Phenomenon in genetics that three or more alleles (example: A, a1) occur for a singular gene. A diploid plant contains just two alleles from this allelic series. As a result more than two phenotypes occur. Multiple alleles is a type of a non-Mendelian inheritance pattern. Note: For both multiple alleles and epistasis a 3:1 segregation…
