Incompletely dominant inheritance
WebCodominance. A variation on incomplete dominance is codominance, in which both alleles for the same characteristic are simultaneously expressed in the heterozygote.An example of codominance occurs in the ABO blood groups of humans. The A and B alleles are expressed in the form of A or B molecules present on the surface of red blood cells. WebMar 5, 2024 · Incomplete Dominance. Incomplete dominance occurs when the phenotype of the offspring is somewhere in between the phenotypes of both parents; a completely dominant allele does not occur. For example, when red snapdragons (C R C R) are crossed with white snapdragons (C W C W), the F 1 hybrids are all pink heterozygotes for flower …

WebFigure 19.7. 4: The wavy hair on this labradoodle is caused by incomplete dominance. (Credit: Localpups, Flickr) Another example of incomplete dominance is the inheritance of straight, wavy, and curly hair in dogs. The KRT71 gene is used to synthesize the keratin 71 protein. Genes in the KRT family provide instructions for making proteins ... WebIn reality, being dominant or recessive is relative. An allele may be recessive to one allele but dominant to another. Which means if one particular locus can hold three alleles, say K k1 and k2, where K is dominant to both k1 and k2. Suppose a person has alleles k1 and k2, they can show co-dominance, incomplete dominance or complete dominance.
