WebThe steps leading up to meiosis are similar to those of mitosis – the centrioles and chromosomes are replicated. The amount of DNA in the cell has doubled, and the ploidy of the cell remains the same as before, at 2n. In meiosis I, the phases are analogous to mitosis: prophase I, metaphase I, anaphase I, and telophase I (below figure). WebMeiotic recombination is initiated by programmed DNA double-strand breaks (DSBs) generated by the Spo11 protein. In budding yeast, five other meiotic-specific proteins are also required for DSB formation, but, with rare exception, orthologs had not been identified in other species.
