Alternate forms of a gene are called alleles.
A dominant trait is expressed when two different genes for the same trait are present.
the number of genes that usually determine a trait
Mendel identified the trait of dominance in certain genes.

An inherited trait is typically determined by multiple genes working together. The exact number of genes involved can vary depending on the trait. In many cases, dozens to hundreds of genes may contribute to a single inherited trait.
