A pea plant with round seeds (RR) is crossbred with another pea plant with wrinkled seeds (rr). What is the probability of producing offspring with genotype Rr? 25% 50% 75% 100%
100% -- if you do a punnet square with RR x rr, all of the possible genotypes will be Rr, meaning that the offspring produced will be heterozygous (Rr).
