Question

which is a non - mendelian trait? a. a trait with two alleles b. a trait controlled by many genes c. a trait controlled by one gene d. a trait with a clearly dominant form

Explanation:

Mendelian traits follow simple inheritance patterns controlled by one gene with dominant - recessive relationships. Non - Mendelian traits, like polygenic traits, are controlled by multiple genes. Traits with two alleles, controlled by one gene, or with a clearly dominant form follow Mendelian inheritance. A trait controlled by many genes is non - Mendelian.

Answer:

B. A trait controlled by many genes
