When the $F_1$ hybrid $Tt$ is crossed with the recessive parent $tt$,it is a case of....

$A$ $1: 1$ phenotypic ratio in a test cross indicates that the

Find out the percentage of dominant phenotype in a cross between $Pp$ and $Pp$. ($P$ = dominant,$p$ = recessive) (in $, \%$)

If a cross between two individuals produces offspring with $50\;\%$ dominant character $(A)$ and $50\;\%$ recessive character $(a),$ then the genotypes of the parents are:

$BB =$ alleles for black coat colour
$bb =$ alleles for brown coat colour
If the offspring of a cross between a black mouse $(BB)$ and a brown mouse $(bb)$ are allowed to interbreed,find the percentage of black-coated mice in the $F_2$ generation.

In a monohybrid cross,if you get a $3:1$ ratio,it denotes that:
