WebbMeiosis has several mechanisms that increase the genetic diversity of gametes produced Both crossing over and independent assortment (random orientation) result in different combinations of alleles in gametes Crossing over Crossing over is the process by which non-sister chromatids exchange alleles Process: Webbwhat are the fundamental characteristics of meiosis I? - 1st meiotic division - homologous chromosomes pair up & wrap around each-other at bivalent - pressure builds & thus equivalent portions of chromatids may break off either chromosome & be exchanged - homologous pairs separated by end of division via pulling apart with spindle fibres
