Detailed explanation-1: -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.
Detailed explanation-2: -Heredity refers to the genetic heritage passed down by our biological parents. It’s why we look like them! More specifically, it is the transmission of traits from one generation to the next. These traits can be physical, such as eye colour, blood type or a disease, or behavioural.
Detailed explanation-3: -In the 19th century, it was commonly believed that an organism’s traits were passed on to offspring in a blend of characteristics ‘donated’ by each parent. Heredity was poorly understood in general, and the concept of a gene did not exist at all.
Detailed explanation-4: -Genetics is the study of heredity. Gregor Mendel’s work in the middle of the 19th century is where genetics got its start. Mendel had proposed that characteristics were passed down as distinct units of inheritance.
