Chromosomes/DNA Mutations

Chromosomes/DNA Mutations. Chromosome Mutation. Mutations are permanent gene or chromosome changes that will be passed on to offspring if they occur in a gamete Two categories of chromosome mutation-Those that affect the # of chromosomes and those that affect the structure of the chromosome.
