Effect of natural selection on phenotypic variation

Evolution takes place through natural selection, which was observed by Charles Darwin. Natural selection affects he genotypic make-up of the organsims, which basically control their phenotype. Effect of natural selection is different on all traits, and depends upon the organsim as well as environment. The environmental conditions affect the genetic make up and random mutations can occur in them, which might help them in surviving in a particular environment. In this case, only the mutated organisms will be able to thrive and populate further and hence are selected over others.

Cell division is important to single celled organisms because it allows the cells to reproduce. through cell division, cells make exact copies of themselves. when single celled organisms go through cell division, they make exact copies of themselves which is how they reproduce.
