Question

In a pea plant, the trait of flowers bearing purple colour (PP) is dominant over white

colour (pp). Explain the inh
eritance pattern of F 1 and F 2 generations with the help of a

cross following the rules of inheritance of traits. What is the (i) phenotypic and (ii) genotypic ratio obtained

in F2 generation?
