Question

The percentage of true breeding plants in the F2 generation of a monohybrid cross is ...........

• A. 10
• B. 30
• C. 50
• D. 70

Answer 1

The correct option is C 50

In F${}_2$ generation, the plants obtained have the following genotypes for any monohybrid cross:

TT Tt Tt tt

Here, TT and tt are true breeding because these are homozygous.

So, the percentage of true breeding comes out to be 50%

Hence, the correct answer is '50'.
