Traits controlled by a single gene.

Traits influenced by environmental factors only.

Traits determined by multiple genes working together.

Traits that are always dominant.

They change the genetic code of the trait.

They alter the expression of the genes without changing the genetic code.

They make the traits non-Mendelian.

They eliminate the influence of genes entirely.
