Question

Which of the following is true for progenies of F4 generation of monohybrid cross?
1. 6.25% pure and 93.75% hybrid
2. 6.25% hybrid and 93.75% pure
3. 12.5% pure and 87.5% hybrid
4. 12.5% hybrid and 87.5% pure

Answer 1

the ans is option 4
f4 generation is same as that of f3 generation so the ratio will be genotypic ratio will be 3:10:3

Answer 2

The correct ans is option 4.

Because,

f4 generation is same as that of f3 generation so the ratio will be genotypic ratio will be 3:10:3.

Monohybrid cross is this cross which is based on the first law of genetics i.e Law of Segregation. A monohybrid cross is a mating between two organisms with different variations at one genetic chromosome of interest. The character being studied in a monohybrid cross are governed by two or multiple variations for a single locus.
