Question

what is an example of many genes contributing to a continuum of phenotypes for one trait? polygenics codominance epistasis pleiotropic

Explanation:

• Polygenics (polygenic inheritance) involves multiple genes contributing to a trait, resulting in a continuum of phenotypes (e.g., human height, skin color).
• Codominance is when both alleles in a heterozygote are fully expressed (e.g., AB blood type), not related to multiple genes for a continuum.
• Epistasis is when one gene's expression modifies another gene's expression, not about multiple genes for a phenotypic continuum.
• Pleiotropic refers to one gene affecting multiple traits, not multiple genes for one trait's continuum.

Answer:

polygenics
