Meiosis plays an important role in the process of natural selection, as it allows DNA to replicate.
Humans directly affect artificial selection. They do this by selecting the specific traits that they prefer which they cannot don in a natural selection.
Non-existent. Biological evolution is mediated by natural selection, and, ultimately, by the very laws of physics themselves. Chance may play *some* role in the process, but it is not all of the process.
Meiosis is the reproduction of the gametes or sex cells. So I'd go with meiosis.
it is formed by meiosis. At first the spermatazoa go through mitosis making two spermatocytes. which then goes through meiosis producing 4 spermatids which then go through spermogenisi n make 4 sperm cells
The direction evolution takes is primarily determined by natural selection. This process favors traits that enhance an organism's survival and reproductive success, causing those traits to become more common in subsequent generations. Additionally, environmental factors play a role in shaping evolution by exerting selective pressures that favor certain adaptations over others.
Disruptive Selection
The environment is the '' natural selector. ''
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.

Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.

First, I should mention that 'micro-evolution' is not a process in itself. Rather, it is a perspective on the effects of evolution. 'Micro-evolution' is those effects seen from close-up; by 'zooming out' one sees those same results in a wider scope called 'macro-evolution'. All evolution is driven by genetic variation and natural selection. Natural selection drives evolution by filtering out some variations while promoting others, thereby directing the slow change of morphology and behaviour of populations.
There are more animals alive than can possibly live, so they compete and struggle for survival. The more of that kind of stress there is on a species, the more natural selection will come into play and filter them into smaller numbers of those most able.
