Children born with semi-curly or wavy hair are example of individuals exhibiting incomplete dominance because the crossing of parents alleles both straight and curly hairs to produce such offspring. Thus, incomplete dominance occurs to produce an intermediate trait between the two parent traits. As for the example of codominance in human, it would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father they have blood type AB.
