Assertion: Protoplast fusion is one of the major advantages of tissue culture
Reason: The naked protoplasts of two different plants fuse to form a hybrid.

A

Assertion is correct, reason is correct, reason is a correct explanation for assertion.

B

Assertion is correct, reason is correct, reason is not a correct explanation for assertion

C

Assertion is correct, reason is incorrect

D

Assertion is incorrect, reason is correct.

Text Solution

Verified by Experts

The correct Answer is:
B
An important technique of tissue culture, somatic hybridization results in the production of somatic hybrid plants. Two different plant varieties each with a desirable character can be made to undergo protoplast fusion, which further can be grown intoa newplant.

Assertion :- According to Mendel, a dihybrid cross is the multiple of two monohybrid crosses. Reason :- When two pairs of traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters.
