Question

Explain incomplete dominance with suitable example.

Answer 1

In incomplete dominance, neither allele is completely dominant over the other. Instead, the heterozygous phenotype is an intermediate (blend) of the two parental traits.

Example: Snapdragon Flower Color

• When a red-flowered plant (RR) is crossed with a white-flowered plant (WW), the offspring (RW) have pink flowers instead of red or white.
• This blending of traits shows that neither allele is completely dominant.
