Question

1. a wrinkle - seeded plant (rr) is crossed with a round - seeded plant (rr). wrinkle - seeded plant round - seeded plant genotype probability (%) phenotype probability (%) rr round seeds: rr wrinkled seeds: rr

Explanation:

Step1: Determine gametes

The wrinkle - seeded plant (rr) can only produce gametes with 'r'. The round - seeded plant (Rr) can produce gametes with 'R' and 'r'.

Step2: Create Punnett square

	r	r
r	rr	rr

Step3: Calculate genotype probabilities

For RR: 0% (no combination gives RR). For Rr: $\frac{2}{4}=50\%$. For rr: $\frac{2}{4}=50\%$.

Step4: Calculate phenotype probabilities

Since R is dominant (round) and r is recessive (wrinkled). Round seeds (Rr): 50%. Wrinkled seeds (rr): 50%.

Answer:

Genotype Probability (\%):
RR: 0
Rr: 50
rr: 50
Phenotype Probability (\%):
Round Seeds: 50
Wrinkled Seeds: 50
