WebSome mutations can be harmful. A change in the gene might produce a faulty or non-functioning protein, resulting in a genetic disease, such as cystic fibrosis. WebSex can introduce new gene combinations into a population and is an important source of genetic variation. You probably know from experience that siblings are not genetically identical to their parents or to each other (except, of course, for identical twins). That's because when organisms reproduce sexually, some genetic "shuffling" occurs, bringing …
WebThere are many different ways that DNA can be changed, resulting in different types of mutation. Here is a quick summary of a few of these: Substitution A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G). Such WebGenetic variation is the difference in DNA sequences between individuals within a population. ... Only variation that arises in germ cells can be inherited from one individual to another and so affect population dynamics, and ultimately evolution. Mutations and recombination are major sources of variation.
