Meiosis. Studies with the budding yeast Saccharomyces cerevisiae indicate that inter-sister recombination occurs frequently during. The two chromatids of each sister chromatid pair are segregated into separate cells in both mitosis and meiosis. But they remain together throughout the first. Sister chromatids are two identical copies of a single replicated chromosome ( chromatids of homologous chromosomes) during meiosis I. In.
In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. Occasionally, genetic material is exchanged between non-sister chromatids during meiosis, allowing for new arrangements of genes to be passed to the. DNA is replicated before meiosis so that all chromosomes consist of two sister chromatids.
