Answer :
The sister chromatids are unlinked is the correct answer.
A sister chromatid is one that has two identical copies of a chromosome that are connected by a common centromere during chromosome DNA replication. In other words, a sister chromatid can also be thought of as "one-half" of a chromosome that has been duplicated. A dyad is a pair of sister chromatids. When all of the chromosomes in a cell are replicated during the synthesis (S) phase of interphase, a full pair of sister chromatids is produced. During mitosis or the second stage of meiosis, the two sister chromatids split apart into two distinct cells.
