MONOHYBRID CROSSES WITH DOMINANCE a. In corn plants, plant height is controlled by one gene with two alleles. How many alleles that control the trait for height are present in each cell nucleus of a corn plant? _______________________________________________ How many alleles that control the trait for height are present in the nucleus of each gamete formed by a corn plant? ______________________________________________________________________________________ b. Indicate the genotypes of these corn plants: c. Indicate the genotypes of possible gametes of these corn plants: d. Determine the predicted phenotype ratio in progeny of a cross between two heterozygous tall corn plants. Parent phenotypes __________________ × ____________________ Parent genotypes __________________ ____________________ Gametes ________ _________ _________ _________ Punnett square ________ ________ e.
