(A) The genotypic ratio of a monohybrid cross is $1:2:1$ for $TT, Tt,$ and $tt$ genotypes.This ratio corresponds to the expansion of the binomial expression $(ax + by)^n$,where $n$ represents the number of gene pairs involved.For a monohybrid cross,$n = 2$ (as it involves one pair of alleles,$T$ and $t$,resulting in $1TT : 2Tt : 1tt$).Therefore,the expression is $(ax + by)^2 = a^2x^2 + 2abxy + b^2y^2$,which mathematically represents the $1:2:1$ ratio.

The $1/4 : 1/2 : 1/4$ ratio of $TT : Tt : tt$ can be depicted mathematically by the binomial expression (ideally):
