The Basics of Genetics
Genetics is the branch of biology that deals with heredity—the passing of traits from parents to offspring—and the variation of inherited characteristics. Understanding genetics is essential to grasp how life functions, evolves, and adapts.
What Is DNA?
Deoxyribonucleic acid (DNA) is the molecule that carries genetic information. It is composed of two strands forming a double helix structure. DNA contains the instructions needed for an organism's development, functioning, growth, and reproduction.
Genes and Chromosomes
- Genes: Segments of DNA that code for specific proteins, influencing traits.
- Chromosomes: Structures within cells that contain many genes; humans typically have 46 chromosomes in each cell.
The Role of Genes in Inheritance
Genes inherited from parents determine physical traits such as eye color, hair type, and height, as well as susceptibility to certain diseases.
