5 days ago · Meiosis is a kind of cell division where the parent cell can make four genetically different haploid cells. This genetic variation can come from crossing-over, which occurs during one of the steps of meiosis. As shown in the image in the question, this involves swapping of segments of homologous chromosomes.

3 days ago · Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent). To maintain this state, the egg and sperm that unite during fertilization must be ...

3 days ago · Draw your pop-bead chromosomes as they appear after meiosis I on the two nuclei labeled “After Meiosis II” of Figure 10-3. Your diagram should indicate the genetic (chromatid) complement before meiosis and after each meiotic division, note the stages of each division. Remember that meiosis takes place in both male and female organisms.
