WebDec 21, 2024 · Prophase I: During prophase of meiosis I, the chromosomes join in homologous pairs. Homologous chromosomes (aka homologs) are the same length, and carry genetic information (genes) for the same traits, but not necessarily the same versions (alleles) of the gene. For example, human chromosome #19 contains a gene for eye color. WebS is the period of DNA synthesis, where cells replicate their chromosomes. G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. M is the actual period of cell division, consisting of prophase, metaphase, anaphase ...
