Question

A cross between F1 hybrid and any one of parent is

• A. Monohybrid cross
• B. Dihybrid cross
• C. Back Cross
• D. Test Cross

Hint:

Use a Back Cross to recover elite parental traits in breeding, and use a Test Cross specifically to determine the genotype of an unknown dominant phenotype.

Answer 1

The Correct Option is C

Step 1: A back cross is a cross between an $F_1$ individual (hybrid) and any of its original parents (dominant or recessive).
Step 2: If the $F_1$ hybrid is crossed specifically with the recessive parent, it is called a test cross.
Step 3: Therefore, every test cross is a back cross, but not every back cross is a test cross.
