In corn, pigmented aleurone (R) is dominant to colorless aleurone (r), and green plant color (G) is dominant to yellow (g). A plant that is heterozygous for both characters is testcrossed to a homozygous recessive for both genes (rrgg). The following progeny are produced: Group Group 1 Group 2 Group 3 Group 4 Phenotype pigmented aleurone; green plant pigmented aleurone; yellow plant colorless aleurone; green plant colorless aleurone; yellow plant heterozygous plant was Number [Select] 85 9 8 Based on the results of this cross, the parental classes of offspring are groups [Select] and the genotype of the 95
