Assertion: The two chromosomes of each bivalent split and go to the opposite ends of the cell.
Reason: This is why the sister chromatids are fused together.
A
B
C
D
Both Assertion & Reason are true and the reason is the correct explanation of the assertion.
During meiosis 1, the homologous pair of chromosomes is divided, transforming the diploid cell into a haploid. It is divided into several stages, including prophase, metaphase, anaphase, and telophase. The two chromosomes of each bivalent split and go to the opposite ends of the cell. The sister chromatids are linked together.
Option 1 is the correct answer.
