In this case, all of these phases except the last phases (anaphase and telophase) have duplicated chromosomes. In the final phases, the replicated chromosomes will split in order to produce the daughter cells.

alagy and Early Develapment Leberatory 2. Identify Homologous Chromosomes and Sister Chromatids in appropriate phases. What are homologous chromosomes? Are they present in all cells? If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II?
