| Description: Hypothetical segregation of three pairs of chromosomes in meiosis I. Maternal chromosomes are pink; paternal, blue. Which chromosome of each pair gets packaged into which of the two new nuclei that form at telophase I is random. For simplicity, no crossing over occurs in this example, so all sister chromatids are identical. 1 The four possible alignments of three pairs of chromosomes in a nucleus at metaphase I. 2 Resulting combina- tions of maternal and paternal chromosomes in the two nuclei that form at telophase I. 3 Resulting combinations of maternal and paternal chromosomes in the four nuclei that form at telo- phase II. Eight different combinations are possible. Picture Stats: Views: 91 Filesize: 381.97kB Height: 1062 Width: 2166 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=48834 |
