Meiosis I is dedicated to forming two Haploid(half chromosome) cells bby separating each pair of chromosomes (one of each type in each cell) and the recombination, or shuffling of genes on each chromosome with its pair by crossing over, While Meiosis II is meant to split the individual chromatids in the haploid cells to create a total or 4 daughter cells
