Aerosolized BC-819 inhibits primary but not secondary lung

Interac-tion between gene combinations of two and three loci was observed by Sharma et al. (2003) in a study of spike length inheritance in durum wheat plants. At normal and late sow-ing, digenic epistatic effects predominated compared to ad-ditive and dominance effects. In a study of mungbean An example of epistasis is pigmentation in mice.

The chart below gives an example of color in a species of bee. This does not show epistasis, but rather is meant as an example to introduce the idea of different combinations of alleles leading to different phenotypes. It is worth noting that some combinations, although different, can result in the same phenotype.

White fruits are produced by a domain epistatic allele 'W'. At another locus 'Y' for yellow   The examples of epistasis given above result from double mutant analyses using severe loss-of-function recessive alleles. Epistasis analysis is based upon the  Epistasis Example.

In panel b the effect of the bb combination masks the effect of the A locus - this is an example of recessive epistasis. In panel c recessive epistasis is combined with dominance of the A allele at the A locus, in panel d both the aa and bb combinations exhibit recessive epistasis.
