Question

Identify the correct combinations:

• A. I and II
• B. II and III
• C. III and IV
• D. I and IV

Hint:

In Mendelian genetics, dominant traits mask recessive traits when both alleles are present.

Answer 1

The Correct Option is D

Step 1: Understanding Dominant and Recessive Traits
Gregor Mendel identified dominant and recessive traits in pea plants:
- Round seed (dominant) vs. Wrinkled seed (recessive)
- Yellow pod (dominant) vs. Green pod (recessive) (Green is dominant)
- Axial flower (dominant) vs. Terminal flower (recessive)
- Yellow seed coat (dominant) vs. Green seed coat (recessive)
Thus, the correct combinations are I and IV.
