Answer:
Biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circulated. The term biogeochemical is a contraction that refers to the consideration of the biological, geological, and chemical aspects of each cycle.
Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
