Since sexually-recreating, diploid, multicellular eukaryotes, human beings rely on meiosis to help you serve a number of important characteristics, like the venture out-of genetic diversity therefore the creation of proper requirements to own reproductive triumph. But not, the primary function of meiosis ‘s the decrease in the fresh ploidy (number of chromosomes) of your own gametes off diploid (2n, or several sets of 23 chromosomes) so you can haploid (1n or you to definitely selection of 23 chromosomes). When you’re areas of meiosis act like mitotic techniques, both solutions out-of mobile section develop distinctly different outcomes. Issues through the meiosis is also prevent embryonic innovation and sometimes end in impulsive miscarriages, hereditary errors, and you will delivery faults such as for example Off problem.
