Link between Meiosis and Genetics

During the crossing over in prophase I of meiosis and the metaphase I, chromosomes share information and during metaphase, separate randomly. This determines the combination of chromosomes and genes that you have as an individual. Genetics determines individual variation (to be different) and survival of the fittest. You MUST have a clear understanding of the genetic terminology in order to study genetics and answer genetic problems.
