If a purple pea plant (PP) is crossed with a white coloured pea plant (PP), will we have white flowered pea plant in the F! generation? Why?

Solution

We will not have white coloured pea plant in F1 generation. Because all progeny plants will have the genotype Pp, and as the P is a dominant allele, that is purple colour is dominant, all the plants with Pp genotype will have purple coloured flowers.
