What is a genomic library?
tells what genes are and where they are.
theory of evolution?
explains hoe genetics within a population base changed one time and that all life shows a common ancester.
What is a stabilizing selection?
it is a average variation that has higher fitness than other variations.
What did Gregor Mendel show?
