Meiosis I: Meiosis I is the first division, the reduction division, of meiosis. There are 4 sub-phases in meiosis I: • Prophase I: During prophase I, homologous chromosomes line up side by side. They are physically in contact with one another.

WebChromosomes become more condensed and visually discrete. Each sister chromatid attaches to spindle microtubules at the centromere via a protein complex called the … WebDuring Prophase I, homologous chromosomes line up with each other and swap small amounts of their DNA from similar regions. Without recombination and crossing over, all alleles on a single chromosome would be inherited together. This system creates new gene combinations which increases our capacity (as a species) to respond to …
WebIn metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense. WebIn the third step of mitosis, called metaphase, each chromosome lines up in a single file line at the center of the cell. By this point in time, the membrane enclosing the nucleus has dissolved, and mitotic spindles have attached themselves to each chromatid in all the …

WebThis is different from the way chromosomes line up single file in mitosis and metaphase II (in meiosis II). The pairs line up in random order in metaphase I, which means that each parental homolog (maternal or paternal) can line up to either pole of the cell.
