Which of the following is an example of a type of chromosomal mutation?
duplication
substitution
insertion

The answer to the question stated above is Duplication. 
Duplication is one of the chromosomal mutation whereby  a segment of chromosome is copied twice, resulting in extra allele. 

Chromosomal mutation  involves the change in chromosome structure which  changes the composition or location allele. 
Other chromosomal mutation includes: 

Deletion - occurs when a segment of chromosome is broken off and lost. 
Inversion - happens when a segment of chromosome is broken off and reattach itself in inverted position. 
Translocation - takes place when a segment of chromosome is broken off and reattach at different point. 

It may have some of the same features that it’s mother does but, it may have some of the same features that it’s father has as well.
