A) primrose
B) Mirabilis
C) Helianthus
D) China rose
Correct Answer: B
Solution :

It simply means that two genes or allelomorphic pair are not related as dominant or recessive, but each of them expresses itself partially. For example, in 4 Oclock plant (Mirabilis jalapa), when plants with red flower (homozygous, RR) are crossed with plants having white flower (homozygous, rr), the heterozygous \[{{F}_{1}}\]-hybrid (Rr) bear pink flower.
