Questions below are based on the following information. A scientist who is interested in genetics cross-pollinates some foxglove plants to investigate what color the flowers of their offspring will be. She draws a Punnett square to display all the possible combinations of alleles when two hybrid foxglove plants are crossed to help her determine the possible genotypes of the offspring. P represents the dominant allele for purple flowers, and p represents the recessive allele for white flowers. The genotype of one parent plant is shown on the top of the square, and the other parent’s genotype... Show more
