Question

1. in another one of mendels experiments, he crossed the offspring. two pea plants with purple flowers (pp) were crossed. purple flowers purple flowers p p p p genotype probability (%) phenotype probability (%) pp purple flowers pp white flowers pp

Explanation:

Step1: Fill in the Punnett square

	P	p
p	Pp	pp

Step2: Calculate genotype probabilities

• For \(PP\): There is \(1\) out of \(4\) squares, so the probability is \(\frac{1}{4}=25\%\)
• For \(Pp\): There are \(2\) out of \(4\) squares, so the probability is \(\frac{2}{4} = 50\%\)
• For \(pp\): There is \(1\) out of \(4\) squares, so the probability is \(\frac{1}{4}=25\%\)

Step3: Calculate phenotype probabilities

• Purple flowers (\(PP\) or \(Pp\)): \((25\%+50\%) = 75\%\)
• White flowers (\(pp\)): \(25\%\)

Answer:

Genotype Probability (\%):

• \(PP\): \(25\%\)
• \(Pp\): \(50\%\)
• \(pp\): \(25\%\)

Phenotype Probability (\%):

• Purple Flowers: \(75\%\)
• White Flowers: \(25\%\)
