Tetrad and chromatid pair are two conditions utilized to explain various mixtures of chromatids of your bivalent. Typically, bivalent is a pair of homologous chromosomes, which pair all through meiosis. Also, they've got now undergone DNA replication.
In the meantime, the chromatid pair is The 2 sister chromatids in a certain chromosome which has gone through DNA replication during the S phase of your interphase. In this article, the cohesin proteins are chargeable for Keeping The 2 sister chromatids collectively. As a result, the primary difference between a tetrad in addition to a chromatid pair is the type of sister chromatids and their job.
