Chromatids/Chromosomes clearly visible in diplotene stage of meiosis. During this phase the two homologous chromosomes begin to migrate apart as the 'synaptonemal complex' disintegrates between the two chromosomal arms and they begin to repel one another.

WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a … WebDuring pachytene of meiosis-I, the paired chromosomes of each bivalent condense and become more distinct. Further, sister chromatids in each chromosome become distinct due to the appearance of a longitudinal furrow. Thus, each bivalent clearly appears as a tetrad consisting of four chromatids.
