Practice Questions

Question 1

In a species of flowers, petal color is determined by incomplete dominance. A red-flowered plant (RR) is crossed with a pink-flowered plant (RW). What is the expected genotype ratio of the offspring?

Question 2

In a codominant inheritance pattern, what is the expected phenotype ratio of offspring from a cross between an individual with genotype IAIB and an individual with genotype IBi in the ABO blood group system?

Question 3

In a polygenic trait influenced by two genes (A and B), each with two alleles (A, a and B, b), how many different phenotypic classes can be observed if each dominant allele contributes equally to the trait?

Question 4

In a case of incomplete dominance, if a plant with genotype RW (pink flowers) is crossed with a plant with genotype RW (pink flowers), what is the expected phenotype ratio of the offspring?

Question 5

If a person with type A blood (genotype IAIA or IAi) has a child with a person with type AB blood (genotype IAIB), what is the probability that the child will have type B blood?
