Question

Which statement best describes human eye color?
an incompletely dominant trait that follows non-Mendelian inheritance patterns
a polygenic trait that follows non-Mendelian inheritance patterns
an incompletely dominant trait that follows Mendelian inheritance patterns
a polygenic trait that follows Mendelian inheritance patterns

Answer 1

a polygenic trait that follows non-Mendelian inheritance patterns

Human eye color is controlled by multiple genes (e.g., OCA2, HERC2 and others) that influence melanin amount and distribution, with gene interactions (epistasis) producing a continuum of colors rather than simple Mendelian dominant/recessive or single-gene incomplete dominance.
