In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If two red-eyed heterozygous flies (Rr) mate together, what are the possible genotypes of their offspring? (Hint: You many want to complete a Punnett square.) RR and Rr Rr only RR and rr RR, Rr, and rr

    This is easy because they have not asked us to find the ratios. U just have to look at it without going for a punnet suqare.

    how? - From both the parental genotypes u get R and r gene that does mean that u can have RR , rr and Rr both right?
