Odile struck Sunday evening near Cabo San Lucas as a Category 3 hurricane, with winds at 125 mph, the National Hurricane Center in Miami reported.

Here's what happens: 1  At first the cells have the same number of chromosomes as mitosis. DNA replication occurs, giving a total of 46 chromosomes (or 23 chromosome pairs) and 92 chromatids (or 46 chromatid pairs). 2  Meiosis I: In meiosis I, the homologous chromosomes separate.
In meiosis, as in mitosis, the maternal and paternal homologues are replicated during DNA replication yielding two pairs of sister chromatids. After the first cell division, each of the resulting cells contains a pair of sister chromatidsâ-one maternal pair and the other paternal.
