Introduction Genetics is the study of units of heredity. Genes determine almost everything about what makes humans humans and genes are passed from parent to offspring‚ because genes have a strong influence on all organisms. Genetics a very broad scientific discipline and the father of genetics is Gregor Mendel. Gregor Mendel studies how genes were inherited in pea plants by crossbreeding thousands of those and discovering their patterns and characteristics. In 20th century the technology has advanced

Genetic testing has been able to help many people by allowing scientist‚ and doctors identify the numerous genes that individuals carry and specific genes that are at risk of being passed down to an offspring. Genetic testing has enabled physicians identify many disorders caused or triggered by various genes that can harm individuals carrying the unwanted genes. Genetic screening can assist the public by treating those people that show to be at higher risk for preventable conditions. While many scientist
