-deletion
-duplication
-inversion
-translocation

5

What is point mutation

Change in only one base

6

What is a frame shift mutation

One or more bases is inserted or deleted

7

What is a deletion mutation

Loss of all or part of chromosome

8

What is a duplication mutation

Segment of a chromosome is repeated

9

What is an inversion mutation

Part of the chromosome is reversed of its usual direction

10

What is translocation mutations

Part of one chromosome breaks off and attaches to another nonhomologous chromosome
