Who is the full genetic formation of a person?

The correct answer is Option 3. 

Key Points

• The full genetic formation of a person refers to the complete set of genetic information that makes up an individual.
• This information is stored in the form of DNA (deoxyribonucleic acid) within the cells of our body.
• The human genome is composed of approximately 20,000 to 25,000 genes, which are segments of DNA that contain instructions for building and maintaining our bodies.
• Each person's genetic formation is unique, except in the case of identical twins who share the same genetic information.
• The genes inherited from our biological parents determine many of our physical characteristics, such as eye color, hair color, and height.
• They also influence our susceptibility to certain diseases, our metabolism, and other aspects of our biology.
