Biology - Incomplete (partial) dominance

Incomplete (partial) dominance

In the case of some genes, one allele is not dominant over the other -
there is partial or incomplete dominance [1] (also known as blending). For
example, flower colour of snapdragons:

PARENT
red

white

FERTILISATION

X

F1

all pink
X selfed (pink x pink)

F2
red
pink
White

RATIO
1:
2:
1

The above ratio can be seen only if large numbers of offspring are
produced.
