The sister chromatids are connected to each other at a point called the centromere. During mitosis, the nuclear envelope dissolves, and sister chromatids separate at the centromere, becoming two individual daughter chromosomes, each now with only one chromatid.
segregation. the separation of allelic genes during meiosis as homologous chromosomes begin to migrate toward opposite poles of the cell, so that eventually the members of each pair of allelic genes go to separate gametes. adjacent segregation. during meiosis adjacent centromeres segregate together.
