Fixation can refer to a gene in general or particular nucleotide position in the DNA chain (locus). In the process of substitution, a previously non-existent allele arises by mutation and undergoes fixation by spreading through the population by random genetic drift and/or positive selection.
Nitrogen fixation is the natural process by which atmospheric nitrogen (N2) is converted into ammonia (NH3), or nitrate forms.This step is important for the continuation of ecosystems because plants depend on nitrates and nitrites, and nitrogen gas is not a usable form for plants to intake.itrogen fixation is the conversion of nitrogen that is found in  the atmosphere into ammonia-which is a form of nitrogen that can  be used by organisms.   Bacteria ar â¦ e cructial in this cycle because it is bacteria that  carry of this fixation. 3 people found this useful. Judy Olmsted. 79,537 Contributions.
