differences between individuals from the same gene pool
Genetic Variation
an extra nucleotide is placed in the DNA sequence
Nucleotide Addition
the condition where both alleles in a cell (organism) are the same

Pleiotropy
occurs when a nucleotide in the DNA is removed and replaced with another nucleotide.
Substitution
A chromosomal change that involves the addition or loss of entire genomes
