WebJul 6, 2024 · Incomplete dominance is a type of inheritance, specifically a type of intermediate inheritance where one allele for a specific trait isn’t entirely expressed (entirely dominant) over its paired allele. The result is a phenotype (expression) where the expressed physical trait is a combination of both of the phenotypes that belong to the alleles. WebJan 22, 2024 · Codominance and incomplete dominance are similar – the former means that two different alleles have the same dominance. The most common example is that of the alleles that govern our blood type. People with heterozygous alleles for A and B blood types have AB type blood rather than either A or B, depending on which is the dominant …
Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism’s resulting physical appearance shows a blending of both alleles.
