Answer:
6)
when homologous chromosomes form chiasmata they are exchanging genetic information.
7)
Gamates contains the half number of chromosomes found in the somatic cells.
8)
Somatic cells are diplod whereas gametes are haploid.
9)
Two genetically similar chromosome one from each parent is known as homologus chromosome.
10)
Sister chromatids are pulled to opposite poles
11)
During the anaphase of the meiosis I the homologous chromosomes are pulled to opposite poles.
12)
Nucleosome is the region of chromosomes made up of multiple loops of chromatin.
