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

The ratio of the possible genotypes of their offsprings are: 1 RR : 2 Rr : 1 rr

The punnet square is a diagram in a square form that is used to forecast the possible genotypes of offspring during breeding experiments.

From the given information:

If two heterozygous flies Rr mate together, the number of the possible genotypes of their offspring can be determined by using the punnet square.

            R        r

R          RR     Rr

r           Rr      rr

Therefore, the genotypes are:

Therefore, we can conclude that the ratio of the possible genotypes of their offsprings are: 1 RR : 2 Rr : 1 rr

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
