The stage in nuclear division following *
anaphase , in which the separated chromatids or the separated homologous chromosomes of bivalents collect at the poles of the spindle and the nuclei of the daughter cells are formed. In *
mitosis and the second division of *
meiosis , the chromatids (now complete single-stranded chromosomes) become surrounded by vesicles as they reach the poles and these eventually merge to form the nuclear membrane. The chromosomes lengthen as they uncoil and the *
chromatin assumes its interphase condition. Nucleoli reappear as they are formed at the nucleolar organizers.
At telophase of the first division of meiosis, the daughter haploid nuclei that form at the poles contain one member only of each homologous pair of chromosomes present in the original mother cell. Each chromosome is divided into two chromatids (genetic recombinants as a result of chiasma formation) held together by a *
centromere. The duration of the following interphase is variable but there is no further DNA replication and the chromosomes remain in a relatively contracted condition. The two daughter haploid nuclei then enter the second division of meiosis.
As daughter nuclei become organized at the poles, a *
cell plate begins to form in the cytoplasm in the equatorial region. This marks the beginning of cell wall formation. In meiosis a cell wall may not form at the end of the first division, the daughter cells being separated by a cell plate only.
