When a heterozygous dominant is crossed with a homozygous recessive,the ratio of the progeny will be:

In the case of inheritance of one gene,the phenotypic ratio of $3:1$ can be explained on the basis of which of the following?

$A$ heterozygous tobacco plant for albinism is self-pollinated,and $1200$ seeds are subsequently germinated. How many of the offspring will have the parental genotype?

In garden pea,round shape of seeds is dominant over wrinkled shape. $A$ pea plant heterozygous for round shape of seed is selfed and $1600$ seeds produced during the cross are subsequently germinated. How many seedlings would have the parental phenotype?

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

In one of the hybridisation experiments,a homozygous dominant parent and a homozygous recessive parent are crossed for a trait. (Plant shows Mendelian inheritance pattern)
