Complete Question
In jimsonweed, purple flowers are dominant to white. Self-fertilization of a particular purple-flowered jimsonweed produces 28 purple-flowered and 10 white-flowered progeny. What proportion of the purple-flowered progeny will breed true?
Solution
Given -
Purple flowers are dominant to white colored flowers
In self fertilization, purple-flowered jimsonweed produces 28 purple-flowered and 10 white-flowered progeny.
Let purple color flower be represented by "P" and white colored flowers be represented by "p"
Pp * Pp
PP, Pp, Pp, pp
one out of four offspring is purple true breed (PP) in terms of genotype
One (PP) of the three types of genotype (PP, Pp, pp) is true purple breed
Thus proportion of the true breed purple-flowered progeny will be
