Text Solution

Verified by Experts

The correct Answer is:
A
To determine the genotype of a tall plant of `F_(2)` generation, Mendel crossed the tall plant from `F_(2)` gneration with a dwarf plant. He called this a test cross. In a typical test cross an organism (pea plants) showing a dominant phenotype whose genotype is to be determined is crossed with the recessive parent instead of self-crossing. The progenies of such a cross can easily be analysed to predict the genotype of the test organism. Normal test cross ratio for a monohybrid cross is `1:1` and for a dihybrid cross is `1:1:1:1`.
