Suppose in a strain of soybeans, high oil (H) content in the seeds is dominant to low oil content (h) and four seeds (E) in a pod is dominant to two seeds (e) in a pod. A farmer
crosses two soybean plants, both with high oil content and four seeds per pod. The
resulting F1 offspring have a phenotypic ratio of 9:3:3:1
(9 High oil / four seeds : 3 High oil / two seeds : 3 Low oil / four seeds: 1 Low oil / two
seeds). What genotype were the parent plants?
OHHEe and HhEE
OHHEE and HhEe
HHEE and hhee
