Wild harebells have blue flowers. Two strains of harebells carry recessive alleles that give the plants white flowers.
(a) Describe a cross to determine whether the white-flower causing alleles in these two strains are variants of the same gene or different genes, and the progeny phenotypes you expect to find in each case.
(b) You results from the cross above indicate that the two strains carry alleles at different genes. What phenotypic ratio do you expect to find among the F2 progeny of a cross between parents of the two strains?
