During which stage of mitosis do the centromeres split
larisa86 [58]
Mitosis is split into 4 phases.
P - prophase
M - metaphase
A - anaphase
T - telophase

During Metaphase, Chromosomes align singly along the metaphase plate.

During Anaphase, kinetochore microtubules shortens and non-kinetochore microtubules lengthens, allowing the chromosomes' centromeres to separate.

Therefore, the answer is anaphase.

P. S. centromeres separates, not split.
