Human Genetics is the branch of biological science that deals with the study of heredity and variation in human beings. It examines how genetic information is transmitted from parents to offspring, how genes influence human characteristics, and how genetic variations arise within populations. Since humans cannot be studied through controlled breeding experiments, human genetics relies on family studies, twin studies, population studies, cytogenetics, molecular biology, and statistical methods. The study of human genetics is important for understanding normal human development, inherited diseases, evolution, and the relationship between genes and the environment. Human genetics has several important branches. Each branch focuses on a particular aspect of human heredity and genetic variation. 1. Classical or Mendelian Genetics: This branch deals with the basic principles of inheritance discovered through the work of Gregor Mendel. It studies the transmission of traits controlled by single genes from one generation to another. Concepts ______ _____ ______ _________ _____ ___ _____ _________.
