During independent assortment, what are separated from one another?
A
Homologous chromosomes
B
Sister chromatids
C
Gametes
D
crossing-over
Explanation: 

Detailed explanation-1: -During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random. This means that all of the maternal chromosomes will not be separated into one cell, while the all paternal chromosomes are separated into another.

Detailed explanation-2: -Figure 3: During anaphase I, the homologous chromosomes are pulled toward opposite poles of the cell. During anaphase I, the microtubules disassemble and contract; this, in turn, separates the homologous chromosomes such that the two chromosomes in each pair are pulled toward opposite ends of the cell (Figure 3).
