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 is the branch of biology that deals with the study of heredity and its biological process. How are genetic diseases passed down? For example, theyre studying the factors that control when genes are active, the mechanisms DNA uses to repair broken or damaged segments, and the complex ways traits are passed to future generations. Genetics is the study of how different qualities, called traits, are passed down from biological parents to child. Researchers estimate that humans have about 20,000 genes. Increasingly, these studies are offering insight into how microbes on and in the body affect our health, sometimes in beneficial ways. Thus, the X- chromosome was termed a sex chromosome and the remaining ones were termed autosomes. Population geneticists pursue their goals by developing abstract mathematical models of gene frequency dynamics, trying .
