In the Pea plant, tall plant height (T) is dominant over short (t). Pure-breeding tall and short plants are crossed. A) If the F1 is self-crossed and 400 F2 plants are raised, how many would be expected in each phenotypic class? B) How many of the F2 would be expected to be pure breeding when selfed?

Expert Solution
Step 1
Introduction:
First law of inheritance known as Law of dominance. In this law, each character is controlled by distinct units called factors, which occur in pairs. If the pairs are heterozygous, one will always dominate the other.
