Question

If a homozygous purple flowered pea plant is crossed with a white flowered pea plant, what are the genotypes of the offspring? Purple (P) is dominant to white (p).

a. 50% PP, 50% Pp b. 100% Pp c. 50% Pp, 50% pp d. purple flowers

Answer 1

B) 100% Pp

Step-by-step explanation:

If the purple flower is homozygous it means that it's not mixed with anything. So it makes it PP. The reason that the p's are capitalized is because it's a dominant trait. The white-flowered pea plant is going to be lowercase because it's not dominant. The image below should help just imagine the a's as p's though.
