Inheritance of One Gene

Question

What percentage of progenies in $F_{2}$ generation of a typical monohybrid cross exhibits homozygous condition?

Easy

A

100%
B

75%
C

50%
D

25%

Solution

If a cross is made between TT and tt. $F_{1}$ generation will have genotype Tt. On selfing we will obtain progenies in the ratio of 1(TT): 2(Tt): 1(tt). From here it is clear that $\frac{2}{4}$ of the progenies have probability of having homozygous genotype. Hence, 50% of the progenies in $F_{2}$ generation of a typical monohybrid cross exhibits homozygous condition.
