Answer to Question 1
In the testes of the male, cells are produced called spermatogonia. Through a four-step process, these cells develop into spermatozoa. During the first step, the chromosomes replicate and remain attached; these are called chromotids. In the next step, the chromotids come together and are matched in pairs; this process is called synapsis. In the third step, the cell divides, the chromosomes are separated, and each cell receives one of each chromosome from each pair. In the final step, the cells separate again, and the chromotids separate and become chromosomes. The end result of this process is that four new sperm cells are produced from the original cell.
