Homologous chromosomes migrate to opposite
WebHomologous chromosomes move to opposite poles during meiosis I so the number of sets of chromosomes in each nucleus-to-be is reduced from two to one. For this reason, meiosis I is referred to as a reduction division. There is no such reduction in … WebThe duplicated chromosomes become shorter and thicker; Duplicated homologous chromosomes pair, and crossing over occurs. The sites of crossing over are seen as crisscrossed nonsister chromatids called chiasmata; Nucleolus and nuclear envelope disappears; Spindle forms as centrosomes migrate to opposite poles
