Crossing of F1 with recessive parent is
A. Back cross
B. Test cross
C. Monohybrid cross
D. Single cross
Answer: Option B
Solution (By Examveda Team)
Option A: Back crossThis is a general term.
It means crossing a hybrid (like our F1) with *any* of its parents (dominant *or* recessive).
Option B: Test cross
This is the correct answer.
A test cross *specifically* means crossing the F1 hybrid with the recessive parent.
It's used to figure out the genotype of the F1.
Option C: Monohybrid cross
This refers to the type of cross, not the specific breeding pattern.
It means crossing individuals to study the inheritance of *one* trait only.
Option D: Single cross
This generally refers to a cross between two inbred lines.
It's not directly related to crossing an F1 with a recessive parent.
Therefore, the best answer is B: Test cross.

The answer must be test cross
The cross between the progeny of F1 and the homozygous recessive parent is known as the test cross and cross between F1 and any parent ( dominant or recessive) known as back cross
