Genetic crossing-over

WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome).

WebJul 17, 2024 · Genetic recombination via crossing over may occur. Chromosomes thicken and detach from the nuclear envelope. Similar to mitosis, the centrioles migrate away from one another and both the nuclear envelope and nucleoli break down. Likewise, the chromosomes begin their migration to the metaphase plate. WebDec 6, 2024 · Crossing Over. When paired homologous chromosomes (one from each parent) exchange DNA during the development of egg and sperm cells, this is referred to as “crossing over” (meiosis). The gametes (egg or sperm) created as a result of this procedure contain new allele combinations, ensuring genetic variety in any progeny.
