Question

pietro has two dogs that are related, and he wants to understand why one of the dogs has tan fur and the other has brown fur. which pattern of inheritance would explain the different fur color in the related dogs? polygenic inheritance codominance incomplete dominance quantitative inheritance

Explanation:

• Polygenic inheritance: Occurs when multiple genes contribute to a single trait. Fur color in dogs is often a polygenic trait, where different combinations of genes from related parents can result in variations like tan and brown fur.
• Codominance: Would show both traits simultaneously (e.g., patches of both colors if it were a codominant trait for fur color, but the question just has two different solid - color fur dogs).
• Incomplete dominance: Would result in an intermediate phenotype (e.g., a blend of tan and brown, not two distinct colors).
• Quantitative inheritance is similar to polygenic inheritance but is more focused on measurable, continuous traits (like height in humans which can be measured on a continuous scale, while fur color is more of a distinct - phenotype polygenic trait in this context).

Answer:

polygenic inheritance
