Chromosome Segregation in Anaphase I is Consistent with Which Statement

Question

Chromosome segregation in anaphase I is consistent with which statement?  
A) The position where crossing over occurs is random.
B) The pole that any one chromosome moves toward is completely independent of the movement of the other 45 chromosomes in human cells.
C) Either partner of a homologous pair of chromosomes may end up at either spindle pole.
D) The sperm that fertilizes the egg is selected at random.
E) The number of crossing over events is random.

Accepted Answer

In anaphase I, homologous pairs of chromosomes separate and move to opposite poles of the cell. The orientation of each bivalent pair and the spindle fibers is random, thus either partner of a homologous pair of chromosomes may end up at either spindle pole. This is consistent with the process of independent assortment, where each homologous chromosome pair segregates independently of the others.
