Question

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

Explanation:

Step1: Create a Punnett square

Parents: \(Pp\times Pp\). The gametes from each parent are \(P\) and \(p\).

	\(P\)	\(p\)
\(p\)	\(Pp\)	\(pp\)

Step2: Calculate genotype ratios

From the Punnett square:

• \(PP\): \(1\) out of \(4\) (\(25\%\))
• \(Pp\): \(2\) out of \(4\) (\(50\%\))
• \(pp\): \(1\) out of \(4\) (\(25\%\))

Answer:

B. \(25\%\ PP\), \(50\%\ Pp\), \(25\%\ pp\)
