what is incomplete dominance

Incomplete dominance is a form of intermediate inheritance in which one allele for a particular trait is not expressed completely over its paired allele. In incomplete dominance, neither of the two alleles is completely dominant over the other, resulting in a phenotype that is a combination of both. For example, in roses, the allele for red color is dominant over the allele for white color, but the heterozygous flowers with both alleles are pink in color. The resulting offspring has a phenotype different from both alleles, i.e., pink color. In incomplete dominance, the dominant allele is expressed in a reduced ratio, and the phenotype is in between the genotype dominant and recessive alleles. Incomplete dominance is a widely studied phenomenon in genetics that leads to morphological and physiological variations.
