Question

select the correct answer.
a chestnut - colored horse mates with a white - colored horse to produce a brown and white spotted offspring. what is the type of inheritance pattern?
a. codominance
b. incomplete dominance
c. polygenic
d. recessive
e. single gene dominant

Explanation:

Codominance is a form of inheritance where both alleles in a heterozygote are fully expressed. In this case, the chestnut - colored horse and the white - colored horse alleles are both expressed in the offspring (brown and white spotted), showing that neither allele is masked and both are equally dominant. Incomplete dominance would show an intermediate phenotype (e.g., a light brown if it was blending). Polygenic refers to traits controlled by multiple genes. Recessive and single - gene dominant do not explain the co - expression of both parental traits.

Answer:

A. codominance
