Question

What is the percentage composition for F, generation in monohybrid cross for height for phenotypic ratio.

a. 50% tall and 50% dwarf.
b. 25% tall and 50% hybrid tall, 25% dwarf.
c. 75% tall and 25% dwarf
d. Both b & e​

Answer 1

Answer:

In F² 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'.
