cross between two heterozygous plants with yellow, round seeds, if the two alleles assort independently, what is/are the
predicted phenotypic ratio(s) of the offspring?
a. all are yellow and round
b. 8 yellow and round: 8 green and wrinkled
c. 9 green and wrinkled: 4 yellow and round: 3 green and round
d. 9 green and round: 3 yellow and round: 3 yellow and wrinkled: 1 green and wrinkled
e. 9 yellow and round: 3 green and round: 3 yellow and wrinkled: 1 green and wrinkled
