Blue flower color is produced in a species of morning glories when dominant alleles are present at two gene loci, A and B. Purple flowers result when a dominant allele is present at only one of the two gene loci, A or B. Flowers are red when the plant is homozygous recessive for each gene (i.e., aabb). Two pure-breeding purple strains are crossed, and all the F1 plants have blue flowers.
 

Check all that apply.
