In a certain species of pea plants, round seeds (R) are dominant over wrinkled seeds (r). If a round seed plant with genotype Rr is crossed with a wrinkled seed plant (rr), what is the expected genotype ratio of the offspring?
1:1
3:1
1:2:1
2:1
The cross Rr x rr results in 1 Rr (round) and 1 rr (wrinkled), giving a genotype ratio of 1:1.
