Question

Write a note on incomplete dominance.

Answer 1

1. Both dominant and recessive genes exhibit partial expression in imperfect dominance.
2. Complete suppression of the recessive gene's expression by the dominant gene is not possible.
3. There is an intermediate expression in the F1 hybrid.
4. For example: The colour of the Mirabilis jalapa's flowers.
   When a white plant (rr) crosses with a red flowering plant (RR), the resultant F 1 hybrid has pink flowers (rr).
