In peas, short height is recessive to tall height, and green pea color is recessive to yellow pea color. A tall pea plant with yellow peas is crossed to a short pea plant with green peas. Suppose that some of the offspring are short, and that some have green peas. What are the genotypes of the two parents?: *(A) One plant is homozygous recessive for both traits, and the other plant is homozygous dominant for both traits.
A) One plant is homozygous recessive for both traits, and the other plant is homozygous dominant for both traits.
(B) One plant is heterozygous for plant height, and the other plant is heterozygous for pea color.
(C) One plant is homozygous dominant for both traits, and the other plant is heterozygous for both traits.
(D) One plant is heterozygous for both traits, and the other plant is homozygous recessive for both traits.
In the cross described in the previous question, suppose that 40% of the offspring turn out tall with yellow peas, and 40% turn out short with green peas. Which mechanism could account for this outcome?: *(A) Incomplete dominance.
(B) Codominance.
(C) Linkage.
(D) Epistasis.
