In each of the following scenarios an individual heterozygou

In each of the following scenarios, an individual heterozygous for the indicated gene or genes is crossed with an identical heterozygous individual. Predict the number of different phenotypes that would be observed among the progeny of such a cross.

Solution

1.Two possible phenotypes in scenario 1 . homozygous RR and heterozygous Rr.

2. Four possible phenotypes Scenario 2 R incompletely dominant over r leads to intermediate character pink shown by 2 off springs and tof the other two one will be dominant red and one recessive white.

3.Scenario three.R and S completely dominant to r and s as there is no interaction parental phenotypes are retained and four possible phenotypes are seen.

4.Scenario four: .R and S completely dominant to r and s and r and S are unlinked three possible phenotypes are seen.

Scenario 5..R and S completely dominant to r and s and r and S are linked three possible phenotypes are seendue to recessive epistasis
