Question

when a red - flowered plant and a white - flowered plant produce an offspring with pink flowers, this is an example of what type of inheritance?
polygenic inheritance
simple dominance
incomplete dominance
codominance

Explanation:

In this inheritance pattern, neither the red nor white flower allele is fully dominant. Instead, the heterozygous offspring shows a blended phenotype (pink flowers) that is intermediate between the two parental traits, which defines incomplete dominance. Polygenic inheritance involves multiple genes for a trait, simple dominance shows only the dominant trait, and codominance shows both parental traits simultaneously (not blended).

Answer:

Incomplete Dominance
