If the cross of a red-flowered plant with a white-flowered plant produces a pink-flowered plant, it is an example of
codominance
incomplete dominance
mutation
linkage
Förklaring
In incomplete dominance, neither allele for a trait is completely dominant, resulting in a heterozygous offspring that displays a blended phenotype between the two parent traits. For example, crossing a red flower plant with a white flower plant will produce pink flower plants. This differs from complete dominance where the dominant allele masks the recessive one, and from codominance where both alleles are expressed.
