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

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?

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?

When a cross is made between a pure tall plant and a pure dwarf plant,what will be the characteristics of the $F_1$ generation?

Expected children of a blue-eyed (recessive) woman and brown-eyed (dominant) man who had a blue-eyed mother are likely to be:

$A$ black dog heterozygous for the colour is crossed with a white bitch,which is recessive homozygous. The progeny will show black to white offspring in the ratio of:
