http://teiteachers.org/during-mitosis-two-new-forms-around-the-chromatids Chromosome segregation occurs at two separate stages during meiosis called anaphase I and anaphase II (see meiosis diagram). In a diploid cell there are two sets of homologous chromosomes of different parental origin (e.g. a paternal and a maternal set). During the phase of meiosis labeled “interphase s” in the meiosis diagram there is a round of DNA replication, so that each of the chromosomes initially present is now composed of two copies called chromatids. Th…

Genetic recombination can … WebThe sister chromatids are then pulled to opposite poles due to the action of the meiotic spindle. The separated chromatids are now individual chromosomes. 9. Telophase II and cytokinesis: The chromosomes complete their move to the opposite poles of the cell. At each pole of the cell a full set of chromosomes gather together.
Web10 Jun 2016 · They are structures of chromosomes at different phases of cell division. When the human cell is not dividing we have Interphase, during which chromosomes inside the nucleus look like a network of threads, called chromatin.
