DNA and Mutations - Understanding Evolution

WebOccasionally a gene changes accidentally. That's called a mutation. The changed gene is passed on to the next generation. Most mutations are bad, but some of them make the organism more successful in its life. … WebMutations are changes in the information contained in genetic material. For most of life, this means a change in the sequence of DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, its physiology — all aspects of its life.

WebSince all cells in our body contain DNA, there are lots of places for mutations to occur; however, not all mutations matter for evolution. Somatic mutations occur in non-reproductive cells and so won’t be passed on to offspring. For example, the yellow color on half of a petal on this red tulip was caused by a somatic. WebNatural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
