If a plant is heterozygous for two independently assorting traits (RrYy) is self-pollinated, what fraction of offspring is expected to show both recessive phenotypes (rryy)?
Question
If a plant is heterozygous for two independently assorting traits (RrYy) is self-pollinated, what fraction of offspring is expected to show both recessive phenotypes (rryy)?
1/4
1/2
1/16
9/16
