During meiosis, programmed double-strand breaks (DSB) allow homologous chromosomes to synapse, crossover, and segregate accurately. Chromosomal errors during meiosis are known to result in infertility or congenital disabilities. Consequently, DNA damage …
WebThe homologous chromosomes separate into different nuclei during meiosis I, causing a reduction of ploidy level in the first division. The second division of meiosis is more similar to a mitotic division, except that the daughter cells do not contain identical genomes because of crossover.
