In a standard monohybrid cross between purple-flowered and white-flowered peas, in which purple flowers are dominant, what fraction of the purple-flowered peas in the f2 generation would you expect to be true-breeding?

75% of the progeny contains purple flower in F2 generation.

Explanation:

The cross between the purple and white flower can be done by the following ways:

( Parents)   PP (purple flower)    ×   pp (white flower)

(Gametes)    P                                           p

F1 genereation            Pp (purple flower)

Selfing of F1 genereation :   Pp     ×    Pp

Progeny of F2 genereation are: PP (purple flower), Pp and Pp( purple flower) and pp (white flower).

The phenotype ration of purple to the white flower is 3:1 or 75% of total progeny is purple flowered.

Thus, the answer is 75%

is this a psat question, if so do not cheat try your best.
