Every living thing produces offspring that are similar to him or her through
sexual and asexual reproduction. You inherit the physical characteristics from your
parents. Sometimes, you may not look like your parents. You may look like your
grandparents because they are a part of your family too.
Genes are contained in the egg cell that comes from the mother and sperm cell of
the father. They do different works like determine the color of your eyes and your hair.
This is what we call heredity. It affects your growth and the color of your hair, skin, and
shape of your eyes, nose, and mouth. Deoxyribonucleic Acid (DNA) is a very important
molecule that acts like a blueprint of your body. It was discovered by James Watson and
Francis Crick in 1953.
