Question

A type of plant that produces red flowers is crossed with a plant that produces white flowers. The allelles for flower color exhibit incomplete dominance and all of their offspring have pink flowrers. If two of the pink-flowered offspring were crossed, which of the ratios would you find in their offspring?

Answer 1

Incomplete dominance shows phenotypes of both dominat and reccessive trait !!

so supppose red is AA
the white is aa
and pink is Aa (heterozygous thus pink)

on crossing Aa to Aa (two pink)

we have ; AA , Aa, Aa, aa

thus 1 red, 2 pink, 1 white
Ratio - 1:2:1
