Genetic Problems A researcher studying petunia plants. These plants have either red or white and this characteristic is influenc
ed by one gene. The alleles are R red (red is dominant) and r white. She crosses to heterozygous red plant with a homozygous white plant. Determine the expected genotypes and phenotypes of the offspring using the steps outlined above.
1 answer:
Well, you would use Punnet squares. Don't forget that heterozygous means that the alleles are different so Rr. Homozygous means that the genotype will have the same genes rr. When you put together the Punnet squares, I always like to determine the percentage of phenotypes possible. In this case 50% of them are going to be white, and 50% of them are going to be red.
