Question

skin color is affected by multiple genes and environmental factors like sunlight. a trait influenced by both genetics and environment is known as a: codominant trait incomplete dominant trait multifactorial character epistatic trait

Explanation:

• Codominant trait: Both alleles are expressed equally (e.g., AB blood type), not related to environmental factors.
• Incomplete dominant trait: Phenotype is intermediate (e.g., pink flowers from red and white), also not involving environment.
• Multifactorial character: Traits influenced by multiple genes (polygenic) and environmental factors, which matches skin color's influence from genes and sunlight.
• Epistatic trait: One gene masks another’s expression, not about environment.

Answer:

multifactorial character
