A plant with red flowers was crossed with another plant with yellow flowers. If F1 showed all flowers orange in colour, explain the inheritance.
Answers (1)
Incomplete dominance of a particular trait over another is seen sometimes which results in the manifestation of both characters in some way. For example, consider genotype of red flowers to be RR and that of yellow flowers to be rr. In F1 generation, all progenies have genotype as Rr. Hence, orange flowers are produced by all plants in F1 generation because red colour does not completely dominate the yellow colour.
