select examples of polygenic traits.
□ fingerprint pattern
□ male-pattern baldness
□ red-green color blindness
□ skin color
□ height

Explanation:

Polygenic traits are controlled by multiple genes, resulting in a range of phenotypes (continuous variation).

• Fingerprint pattern: Influenced by multiple genetic and environmental factors, showing continuous variation.
• Male-pattern baldness: Determined by several genes plus hormonal factors, a polygenic trait.
• Red-green color blindness: A sex-linked single-gene disorder, not polygenic.
• Skin color: Controlled by multiple genes leading to a continuous range of tones, polygenic.
• Height: Influenced by many genes and environment, classic polygenic trait.

Answer:

• fingerprint pattern
• male-pattern baldness
• skin color
• height
