Explain in detail the process of meiosis including the significance of tetrad formation, crossing over, and the Law of Independent Assortment in maintaining chromosome number and genetic variability. Explain the key features that make it different from mitosis.

Expert Solution

Meiosis definition- It is cell division process which occurs in sexually reproducing organisms to form gametes. This process occurs in 2 parts meiosis 1 and meiosis 2.

To simulate Prophase of Meiosis I - Synapsis and Crossing Over: 1. Homologous chromosomes come together and synapse along their entire length. This pairing (synapsis) of homologous chromosomes represents the first big difference between mitosis and meiosis. This pairing will produce two tetrads, each consisting of four chromatids. Entwine the two chromosomes to simulate synapsis. 2. To simulate crossing over, start with your long tetrad and transfer the circles on the red chromatid at the fourth bead or “gene” to...
