1
Q
What is speciation
A
Evolution of a new species from an existing species
2
Q
Inversion mutation
A
Occurs during crossing-over in meiosis
DNA of a single gene is cut in two places, the cut portion is inverted 180° then rejoined to the same place within the gene
Result in non-functional proteins
3
Q
Duplication mutation
A
A whole gene/section is repeated so that two copies appear on the same chromosome
Mutation is not harmful
4
Q
Translocation mutation
A
Section of a gene is cut off and attaches to a separate gene
The cut gene is now non-functional
