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

So here we have two heterozygous organisms that will mate. You can put them into a Punnet square, just to be sure of your answers and to find all possible genotypes :

R r
R RR Rr
r Rr rr

So you have RR, Rr and rr as your possible genotypes.
