Question

According to chromosomal theory of inheritance, the following statements are correct.

A. The maternal chromosomes of both the bivalents always move towards one pole and paternal chromosomes towards another pole.

B. The maternal chromosome of one bivalent and paternal chromosome of another bivalent always moves towards a pole and another combination of paternal of one bivalent and maternal of another bivalent to another pole.

C. The movement of maternal and paternal chromosomes of a bivalent towards respective poles is independent of movement of maternal and paternal chromosomes of another bivalent.
