Genetics is the study of genes and inheritance in living organisms. This branch of science has a fascinating history, stretching from the 19 th century when scientists began to study how organisms inherited traits from their parents, to the present day when we can read the “source code” of living things letter-by-letter.
Genetics, study of heredity in general and of genes in particular. Genetics forms one of the central pillars of biology and overlaps with many other areas, such as agriculture, medicine, and biotechnology. Learn more about the history, biology, areas of study, and methods of genetics.
Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the context of a population. Genetics has given rise to a number of subfields, including molecular genetics, epigenetics, and population genetics.
Genetics is the science of genes and how traits are passed on from one generation to the next. People who study genes are geneticists (juh-net-i-sists). Every living thing has DNA.
This chapter provides fundamental information about basic genetics concepts, including cell structure, the molecular and biochemical basis of disease, major types of genetic disease, laws of inheritance, and the impact of genetic variation.
Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.
The meaning of GENETICS is a branch of biology that deals with the heredity and variation of organisms.
