In monohybrid cross, what is the ratio of homozygous dominant and homozygous recessive individuals in F$$_{2}$$ generation?

A0.04306712963
B2:1
C1:3
D1:1
Correct Answer

Solution

Monohybrid cross :
Genotype : TT x tt
Gametes : T t
F$$_{1}$$ : Tt
Selfing of F$$_{1}$$ : Tt x Tt
Gametes : T, t T, t
F$$_{2}$$ generation : TT, Tt, Tt, tt
Ratio between homozygous dominant and homozygous recessive : 1 TT : 1 tt --> 1 : 1
So, the correct answer is '1:1'
