Codominance

Complete dominance

Incomplete dominance

Sex linkage

Complete dominance

Codominance

Incomplete dominance

Simple recessive

A change in the DNA base sequence

The copying of DNA before division

The folding of a protein

The joining of two gametes

A mutation in a gamete (egg or sperm)

A mutation in a skin cell

Any body-cell mutation

Mutations are never inherited

Genetic engineering takes many generations; selective breeding works in one step

Selective breeding inserts new genes; genetic engineering uses only existing variation

They are the same process

Genetic engineering directly inserts or alters specific genes; selective breeding chooses which organisms reproduce over generations
