Introduction 6B : Meiosis is a process that reduces the Chromosome number in half during the formation of Gametes in animals and Spores in plants Meiosis I - Reduction Division - chromosomal pairs are partitioned so that each Gamete (or Spore) contains a single Haploid (a cell with only one Chromosome set) o Remember that the 46 Chromosomes in a human are split into 23 pairs so normal cells contain two “sets” of Chromosomes Meiosis II - Division in which duplicate Chromatids are separated Fertilization - the process in which Haploid Gametes unite and produce a Diploid Zygote Meiosis produces cells that are different from the original (increases Genetic Variation ) Each Diploid Cell undergoing Meiosis can produce 2n different combinations o N = Haploid Number (23 in humans) Synapsis - a process in which each pair of Chromosomes Unite Crossing Over - a process in which Chromatids of Homologous Chromosomes exchange parts o The relative distance between 2 genes on a Chromosome can be estimated by calculating the percentage of crossing over that takes place between them
