Question

Which of these best describes incomplete dominance

Answer 1

Incomplete dominance refers to a genetic situation in which neither allele is completely dominant over the other in a heterozygous individual. Instead of one allele completely masking the effect of the other, the phenotype (observable traits) is a blend or intermediate of the two parent alleles.

For example, in a plant species where one allele produces red flowers and another produces white flowers, incomplete dominance would result in offspring with pink flowers when the two alleles are crossed. This phenomenon contrasts with complete dominance, where the dominant allele would fully express its trait regardless of the presence of the recessive allele.
