TRANSCRIPT
CHROMOSOMAL MUTATIONS
Mutation: A sudden change in the structure or the amount of genetic material.•Mutations, Crossing Over, and Independent Assortment increase genetic variation in a population.
Target: I will be able to identify the main types of chromosomal mutations.
Pg. 39
Chromosomal Mutation: An abnormal change in the structure of all or part of a chromosome or the number of chromosomes.
Types of Chromosomal Mutations: 1. Deletion: When a piece of chromosome is missing.
2. Duplication/Addition: When a piece of chromosome is added to the homologous chromosome.
3. Translocation: When a piece of chromosome is added to the nonhomologous chromosome.
4. Inversion: When the order of genes is switched in a chromosome.
5. Nondisjunction: When disjunction doesn’t occur correctly during anaphase of meiosis, so the gamete has an extra or missing chromosome.
