It's crucial that certain cells, like reproductive cells, have the correct number of chromosomes in order to function properly. Scientists also know that the DNA that makes up genes is packed into structures called chromosomes, and that somatic cells contain twice as many chromosomes as gametes (i.e., sperm and egg cells). In certain ways, sex chromosomes function differently than nonsex chromosomes. This unique structure of chromosome keeps DNA tightly packed with histone proteins to fit inside the cell and it also helps in giving more stability to it. In most organisms, one chromosome is inherited from the mother and the other is inherited from the father; to ensure that offspring carry traits from both parents.

Last phase, the chromosomes gather at opposite ends of the cell and lose their distinct shapes. Sex chromosome, either of a pair of chromosomes that determine whether an individual is male or female. The genes on each chromosome are arranged in a particular sequence, and each gene has a particular location on the chromosome (called its locus). Chromosomes and genes are just the tip of the iceberg under the fascinating subject of genetics.
