Web1 hour ago · Every cell in our body contains a vibrant population of mitochondria, or, more precisely, of mitochondrial DNA molecules (mtDNAs). Just like members of any population mtDNAs multiply (by replication) and die (i.e., are removed, either by degradation or by distribution into the sister cell in mitosis). An intriguing question is whether all … WebIn random dispersion, the position of each individual is independent of the others, and spacing is unpredictable. Random dispersion occurs in the absence of strong attraction or repulsion among individuals in a population, or when key physical or chemical factors are relatively homogeneously distributed.
