A single yeast cell placed on a solid agar will dividemitotically to produce a colony of about 107cells. Ahaploid yeast cell that has a mutation in the ade2 genewill produce a red colony; an ade2+ colony will bewhite. Some of the colonies formed from diploidyeast cells with a genotype of ade2+/ ade2− willcontain sectors of red within a white colony.a. How would you explain these sectors?b. Although the white colonies are roughly the samesize, the red sectors within some of the whitecolonies vary markedly in size. Why? Do youexpect the majority of the red sectors to be relativelylarge or relatively small?
