Mutations
Mutations
Mutations are changes to the DNA molecule. These changes can be quite small, but still have a big impact on an organism.
Learning Outcome: Describe what a mutation is, how it occurs, and the possible impacts, including examples of mutations in animals species.
Mutations are changes in DNA, and these mutations can be large chromosomal mutations where large amounts of DNA are impacted, or small changes to the DNA molecule.
This video explains what mutation are, how they happen, and how they can lead to the creation of new alleles.

Mutations that arise in species are sometimes sought after and augmented through artificial selection. These goldfish breeds have been bred for over a century. The mutations are so extreme, it is unlikely these animals would have survived for generations in the wild.
The next section examines the structures and functions of animal integumentary systems: skin, hair, and nails.
