WebCrossing Over. During meiosis, when homologous chromosomes are paired together, there are points along the chromosomes that make contact with the other pair. This point of contact is deemed the chiasmata and can … 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. So a change in an organism's DNA can cause changes

WebThe mechanism of evolution is a complex process that includes genetic variation, natural selection, genetic drift, gene flow, and environmental factors. Genetics and epigenetics, on the other hand, are two important mechanisms that contribute to the evolutionary process. Role of Genetics in Evolution. The basis of evolution is genetic variation.
