The F 1 plants were self-pollinated to establish F 2 populations, 697 plants from the D082 × CCMC F 2 population, and 508 plants from the D226 × CCMC F 2 population. The segregation ratios of the F 2 populations were analyzed using the chi-square test (χ …

WebThe alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. Often the biochemical basis of epistasis is a gene pathway in which expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway. An example of epistasis is pigmentation in mice. WebThere are epistatic interactions between at least two genes for rose pigment. The H substance is needed for the proper phenotypic expression of the A, B, and AB blood types in the ABO blood typing system in humans. Individuals who are recessive for the H substance (hh) will have a type O phenotype, even if they have the A and/or B alleles.
