Which of the following is true about the attachment of sister chromatid to kinetochore in this phase?

(a) Each chromosome is bound by 2 spindle fibers at the kinetochore

(b) The sister chromatids seperate

(c) The attachment is at centromere

(d) Chromosomes bound by one spindle give negative signal to prevent cycle progression

This question was posed to me by my school principal while I was bunking the class.

This is a very interesting question from Meiosis 1 Metaphase, Anaphase & Telophase topic in portion Chromosomal Changes During Meiosis of Cytogenetics

Best answer
Right option is (c) The attachment is at centromere

Explanation: In prometaphase 1 the homologous chromosome pair behaves as a single unit. In this case one spindle is attached to one chromosome as a pair and the chromosomes separate not chromatids.
