Question

if a pp plant is crossed with another pp plant, what is (are) the expected genotype(s) in the offspring? a 25% pp, 50% pp, 25% pp b 75% pp, 25% pp c 100% pp d 50% pp, 50% pp

Explanation:

Step1: Set up Punnett - square

A Punnett - square for a cross between two Pp plants has 4 boxes. The possible gametes from each Pp parent are P and p.

Step2: Fill in the Punnett - square

	P	p
p	Pp	pp

Step3: Calculate genotype ratios

There is 1 PP out of 4 (25%), 2 Pp out of 4 (50%), and 1 pp out of 4 (25%).

Answer:

a. 25% PP, 50% Pp, 25% pp
