WebThere are two types of cell division. Mitosis produces two identical diploid daughter cells. Meiosis produces four non-identical haploid gametes (sex cells). WebTwo additional modifications were made to the strains to study Cre/loxP recombination during meiosis. First, since this study involved the analysis of mutations that could differentially affect the timing or ability of cells to proceed through the first meiotic division or result in chromosome missegregation at the MI division, theNDT80 gene was deleted.
