Monogeny

from Wikipedia, the free encyclopedia

Mono genius referred to genetics training of a feature due to a single gene according to the one-gene-one-enzyme hypothesis that the lifetime of Gregor Mendel , however, was not yet known.

Monogeny is the simplest case of gene interaction; in diploid species there are two alleles at the gene location . It forms the basis of Mendel's rules .

An example of monogeny is the AB0 system of blood groups . Examples of monogenic diseases are Martin-Bell syndrome and neurofibromatosis type 1 .

Monogeny is not to be confused with the monohybrid inheritance and the dihybrid inheritance , which is about the consideration of only a single characteristic or the consideration of the possible combinations of two characteristics.
