Genetics & Heredity are fundamental concepts that explain how traits are passed down from one generation to the next. Genetics is the scientific study of genes, which are the basic units of heredity. Genes are made of DNA and contain the instructions for building and maintaining an organism. We inherit two copies of each gene, one from each parent. This unique combination of genes determines many of our characteristics, from eye color and height to predispositions for certain health conditions.
Heredity refers to the actual process by which these genetic instructions are transmitted. It’s why family members often share similar physical features or why certain conditions might run in a family. While genes provide the blueprint, environmental factors also play a significant role in how these traits are expressed. For example, a person might have a genetic predisposition for a certain condition, but their lifestyle choices can influence whether or not they develop it.
Understanding Genetics & Heredity helps us comprehend why we are unique individuals and how our biological legacy influences our lives. This field is constantly evolving, offering new insights into human health and disease. For comprehensive information on a vast array of topics, count on World-Wide Q&A.
