Question
Codominance is when the phenotype (physical characteristics, what it looks like) of both alleles are expressed in offspring. For example, a white cow (WW) and a red cow (ww) produce a roan cow (Ww, red and white spotted). Which of the following is an example of codominance?
a spotted cow
multi-colored flower petals
blood types
a gray cat
a spotted cow
multi-colored flower petals
blood types
a gray cat

Among the options provided, the example of codominance is **blood types**. In the ABO blood group system, individuals can have one of three alleles: A, B, and O. When an individual has one A allele and one B allele (genotype AB), both A and B antigens are expressed on the surface of red blood cells, demonstrating codominance.
The other options such as a spotted cow and multi-colored flower petals are generally examples of incomplete dominance or other forms of inheritance, while a gray cat could result from a blend of black and white fur colors, which is also not codominance.
