Question

Which one of the following cross/es did Mendel perform?

• A. Both Monohybrid and dihybrid
• B. Monohybrid, dihybrid and trihybrid
• C. Monohybrid only
• D. Dihybrid only

Hint:

Mendel's experiments with monohybrid and dihybrid crosses laid the foundation for the principles of inheritance.

Answer 1

The Correct Option is A

Step 1: Understanding Mendel's experiments.
Gregor Mendel conducted experiments on pea plants and performed both monohybrid and dihybrid crosses to study inheritance patterns. Monohybrid crosses examine the inheritance of one trait, while dihybrid crosses examine the inheritance of two traits.
Step 2: Analyzing the options.
(A) Both Monohybrid and dihybrid: Correct — Mendel performed both monohybrid and dihybrid crosses to study the inheritance of traits.
(B) Monohybrid, dihybrid and trihybrid: Incorrect — Mendel's experiments focused on monohybrid and dihybrid crosses, not trihybrid.
(C) Monohybrid only: Incorrect — Mendel also performed dihybrid crosses.
(D) Dihybrid only: Incorrect — Mendel performed both monohybrid and dihybrid crosses.
Step 3: Conclusion.
The correct answer is (A) Both Monohybrid and dihybrid, as Mendel conducted both types of crosses.
