Question

Characteristics determined by an organism's genes

Answer 1

An organism's phenotype is determined by its genotype, but gene expression can be affected by environmental factors. These factors can alter the inherited traits of an organism.

Answer 2

A trait is a specific characteristic of an organism. Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.
