Chromosomes are threadlike, microscopic, molecular components of DNA (nucleic acid and proteins) that are the “building blocks” of life. For example, the X and Y chromosomes are responsible for influencing which sex an embryo will turn out to be. They are also the makeup of a humans genotype, which is a persons unique genetic construct. Chromosomes are essentially blue prints for a persons genetic make up and their phenotype, too, which constitutes a persons observable characteristics based on their genes, such as eye and hair color. Autosomes are the 22 pairs that are codes for genetic traits, which make up 44 chromosomes, plus the two gonosomes. Gonosomes, or sex chromosomes, are what determine sexes. Males have both an X and Y chromosome, while females have two X chromosomes. All-together, humans have 46 chromosomes. Each chromosome has a centromere, which is a “constriction” point that is responsible for dividing the chromosome into two sections. Placement of the centromere gives each chromosome its shape and specific placement of genes. Also, during reproduction, the female egg and the male sperm each contain 23 chromosomes, and when the egg is fertilized, they combine to have the full 46 chromosomes necessary for life.
Chromosomes are especially important in the process of cell division. If chromosomes don’t replicate, new cells cannot be formed, and this will result in no growth and ultimately death. Chromosomes help keep DNA stable in its physical make-up as well as its biological make-up. They help to ensure that DNA is distributed and remade properly. If not, this could lead to serious disorders such as certain types of leukemia and down syndrome. Such problems would be a result of too many, too few, or deformed chromosomes that got messed up during cell division. Chromosomes are also the components of a persons DNA that makes them unlike anybody else.

Hi!!
Here's your answer!!
At the time of cell division chromatin network give rise to small structure called chromosome.
Chromosome plays an important role in the inheritance of characters.(from parents to the children.)
Hope this helps you!!
