The correct answer is D, incomplete dominance.

## Step 1<br />The problem presents a scenario where a black chicken is mated with a white chicken, and the offspring exhibit a blend of both black and white colors, appearing blue. This is a classic example of a genetic inheritance pattern.<br /><br />## Step 2<br />The four options provided are different types of genetic inheritance patterns: codominance, segregation, multiple alleles, and incomplete dominance.<br /><br />## Step 3<br />In codominance, both alleles in a gene pair contribute to the phenotype of the organism. This is not the case here, as the offspring do not exhibit both black and white colors simultaneously.<br /><br />## Step 4<br />Segregation refers to the separation of alleles during the formation of gametes. This is not the case here, as the offspring do not exhibit a separation of alleles.<br /><br />## Step 5<br />Multiple alleles refers to the presence of more than two alleles for a particular trait. This is not the case here, as the offspring do not exhibit multiple alleles.<br /><br />## Step 6<br />Incomplete dominance is a situation where the phenotype of the heterozygous genotype is intermediate between the phenotypes of the homozygous genotypes. This is the case here, as the offspring exhibit a blend of both black and white colors, appearing blue.
