Genetics and Development

Genetics and development are fields that study how traits are inherited and how organisms grow. Genetics focuses on genes, which are units of DNA carrying instructions for building and functioning organisms. These genes determine physical features, health, and other traits. Development is the process by which an organism changes and matures from a fertilized egg into a fully formed individual, involving cell division, differentiation, and growth. Together, genetics and development explain how inherited genetic information guides growth patterns and physical characteristics throughout an organism's life.
