A cross of pea plants, both heterozygous for seed shape and color traits, resulted in progeny in the ratio 9/16 round yellow (R_Y_), 3/16 round green (R_yy), 3/16 wrinkled yellow (rrY_), and 1/16 wrinkled green (rryy)
This result demonstrates that the:
A. alleles responsible for seed color are segregating but those responsible for shape are not.
B. alleles of seed shape and color are segregating independently.
C. phenotypes corresponding to seed shape are segregating 1:2:1.
D. alleles governing seed color display codominance.
E. alleles for seed shape and color are linked.
