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.
Recombination in meiosis. Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.
