Traits That Depend on More Than One Gene

The correct answer to the question is polygenic traits. Here’s a brief analysis:

1. Polygenic Traits: These traits are influenced by multiple genes, each contributing to the phenotype in a cumulative manner. Examples include height, skin color, and weight in humans, which show a continuous range of variation.

2. Pleiotropic Traits: These involve a single gene affecting multiple phenotypic traits. An instance is the Marfan syndrome, where one gene affects various body systems.

3. Codominant Traits: In these traits, both alleles in a heterozygote are fully expressed, like in the AB blood type.

4. Recessive Traits: These traits manifest only when two copies of the recessive allele are present.

5. Incomplete Dominant Traits: These traits display a blend of traits from both alleles (e.g., red and white flowers producing pink offspring).

Conclusion

Polygenic traits result from the interaction of multiple genes, making them the correct choice for the question posed.
