Vocabulary Review
A gene is a small section of DNA that codes for a protein.
Chromosomes are long pieces of DNA that have been condensed. They contain many genes.
Mutations are changes in the DNA.

Review: Types of gene mutations
There are 3 kinds of gene mutations...
Insertion - Adding bases ( + )
Deletion - Removing bases ( - )
Substitution - Changing bases ( = )
Insertions & deletions are frameshift mutations

11
Duplication
Part of the chromosome is "copied & pasted" back into itself.
12
Inversion
Part of the chromosome is flipped so that the genes are reversed in order.
13
Deletion
Part of the chromosome is removed and lost.
14
Translocation
Section of two non-homologous chromosomes are switched.
This is not like crossing over because the pieces are not equivalent!
15
Crossing Over
Crossing over is not considered to be a mutation.
During crossing over, homologous chromosomes exchange equivalent sections of their genes.
This process naturally occurs in Prophase I.
