Genetics notes
... • Mutations: changes that occur in a gene or chromosome. Mutations can occur for a variety of reasons. For example, when chromosomes (genes) separate and reform during meiosis a segment of one gene will sometimes switch places with a segment on the other DNA strand. This is called crossing over and ...
