Question
1. P is a dominant allele for purple flowers and p is the recessive allele that causes white flowers. The
following cross is performed: Pp x pp. What percentage of offspring would you expect to have white
flowers?
2. In peas, T (tall) is dominant to t (dwarf). A homozygous dominant plant is crossed to a heterozygous plant.
What is the expected outcome for the genotype ratio of offspring from this cross? What percentage of
offspring would you expect to be tall?
3. In peas, Y (yellow seeds) is dominant to y (green seeds) and R (round seeds) is dominant to r (wrinkled
seeds). The following cross is performed: YYRr x yyrr. What is the expected phenotype ratio of the
offspring?
