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. It tied as the strongest hurricane on record to make landfall in the Baja Peninsula, matching Hurricane Olivia in 1967, Weather Underground meteorologist Jeff Masters said.
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.
The two meiotic divisions are known as Meiosis I and Meiosis II. Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids, which remain held together through sister chromatid cohesion. This S-phase can be referred to as premeiotic S-phase or meiotic S-phase..
