G11 Pre-AP Biology Mutation is any change to DNA in a cell. If a mutation occurs in a germ cell, it well get passed on to the next generation. Mutations aren't necessarily a detriment, it can also be beneficial or have no effect (silent mutations).

Four main types of chromosome changes are:

• Deletion, where a segment is deleted from the chromosome.
• Translocation, which is crossover between non homologous chromosomes
• Inversion, where a section is inverted 180 degrees.
• Duplication, where a section is repeated.
