Question
The dominant allele for yellow seed color is Y, and the
recessive allele for green color is y. The dominant allele for
round seeds is R, and the recessive allele for a wrinkled
shape is r. If two plants crossed had a RrYy genotype, what
ratios of traits would be observed in the offspring?
Answer
The offspring would have a 3:1 ratio of round to wrinkled seeds and a 3:1 ratio of yellow to green seeds.
