Types of mutations

Types of mutations . Mutations are changes in the genetic material There are two basic types of mutations: Gene mutations - mutations that produce changes in a single gene Chromosomal mutations - mutations that produce changes in whole chromosomes. Gene mutations . Point mutations:

Chapter 13.17- 13.22. 13.17 Endangered species often have reduced in variation. Endangered species have low genetic variability and the diversity in their gene pool makes them less successful Example: Cheetahs suffered severe bottleneck (possibly two)
