WebJul 17, 2024 · Chromosomes condense and attach to the nuclear envelope. Synapsis occurs (a pair of homologous chromosomes lines up closely together) and a tetrad is formed. Each tetrad is composed of four chromatids . Genetic recombination via crossing over may occur. Chromosomes thicken and detach from the nuclear envelope. WebThe process of crossing over occurs during meiosis and involves the exchange of genetic material between homologous chromosomes. This allows for a variety of different combinations of alleles to be generated, which contributes to an increase in the genetic diversity of the children.
