Evolution and Natural Selection

Where do the genes that determine an individual's traits come from?

• An individual can be born with any genes, since genes are random.

• Individuals grow genes specific to their environment.

• Parents pass their genes down to their offspring

• Parents choose which genes their offspring have when each individual is born
