Epistatic inheritance
WebEpistasis or modifier genes, that is, gene-gene interactions of non-allelic partners, play a major role in susceptibility to common human diseases. This old genetic concept has experienced a major renaissance recently. Interestingly, epistatic genes can make the disease less severe, or make it more severe. Is epistasis rare in humans? WebNon-Mendelian inheritance is any pattern in which traits do not segregate in accordance with Mendel's laws. ... This allele is epistatic over some other coat color genes.
