Epistatic group
WebEpistasis refers to genetic interactions in which the mutation of one gene masks the phenotypic effects of a mutation at another locus. [1] Systematic analysis of these epistatic interactions can provide insight into the structure and function of genetic pathways.

H/_ individuals are able to make the substrate for the A and B enzymes, while h/h individuals do not. As a result,h/h individuals always have type O blood. An H/h; /i individual mates with an h/h; B/i individual.

WebIn DRE, any recessive homozigote is epistatic and they all give the same fenotipe. So we look for how many of the F1's genotipes that doesn't has any recessive homozigote then compare to how many of those that has recessive homozigote (epistatic gene, it means all of them have same fenotipe), then we got 9:7.
