WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome). … WebAnaphase I. During this stage of meiosis, the cell starts to lengthen. The two homologs of each chromosome pair separate and move toward opposite poles, drawn by the …

WebJul 6, 2016 · In anaphase II of meiosis, chromatid separation takes place (like mitotic division) . Each chromosome separates in two chramatids which were joined at centromere. Separated chromatids travel to opposite poles. At the end of meiosis II, there are four daughter cells, each with half the number of chromosomes. Answer link. WebThe diagrams below (numbered 1 through 12) represent anaphases of individual cells in meiosis or mitosis in an organism that is geneticially dihybrid (A/a; B/b) for genes on different chromosomes.
