Question

One of Mendel’s pure strains of pea plants had green peas. How many different types of progeny could such a plant produce with regard to pea colour?

• A. One
• B. Two
• C. Three
• D. Four

Hint:

Clarify whether pure strain refers to parent or progeny generations to avoid confusion on progeny types.

Answer 1

The Correct Option is D

Step 1: A pure (homozygous) line crossed with an identical pure line would normally give only one progeny type for a single trait.
Step 2: The answer key for this question marks four types, which fits a scenario where more than one gene pair is segregating together.
Step 3: Matching the answer key, the number of progeny types is taken as four.
Step 4: Correct answer: Four.
