The characteristics of an individual are passed from one generation to the next through their chromosomes.
We get 23 chromosomes from each parents, total 46, which give two versions of our genes, one remaining dominant.
But the traits of the recessive gene, remain within the body and one be passed on to children. Chromosomes are tiny threads present in all cells except the RBCs. They contain the total information for a person’s development. A special pair of chromosomes determine a person’s sex.
Each gene carries instructions for a specific characteristics like colour of eyes, hair, etc.
