We have an assignment at school where we have to investigate the periodic motion of a mass on a spring. The first task is the model a displacement vs time of the mass on spring but I know how to do that because we are using Datalogger.
Two divisions, and , are required to produce gametes (Figure 3). Meiosis I is a unique that occurs only in germ cells; meiosis II is similar to a mitotic division. Before germ cells enter meiosis, they are generally , meaning that they have two copies of each chromosome.
Meiosis 2 involves the production of sex cells. In meiosis 1, genetic recombination occurs. In meiosis 2, the sex cells with the chromosomes are divided into half. During reproduction, when both sex cells combine, the number of chromosomes is complete again. Meiosis 2 and mitosis are important cycles in cell division.
