Web6 okt. 2012 · In a normal mitotic metaphase there are 2n kinetochore pairs, and as you rightly calculated, there will be 96 K-fibres. In meiosis-I there is a tetrad which has 2 kinetochore pairs but the ones in sister chromatids behave as a single unit. So there would be 23 fibres. The fusion of kinetochores of sister chromatids is relaxed in meiosis-II and ... WebThe mitotic spindle consists of two other populations of microtubules: (1) microtubules that do not attach to kinetochores, but also emanate toward the cell center and are called central spindle or non-kinetochore microtubules and (2) microtubules that emanate from the centrosomes circumferentially and anchor at the cell cortex are called astral …
