what is GENETICS and what are its acheivements

Genetics is a core science dealing with DNA chromosomes and genes Gregor Mendel is the father of Genetics He is the one who did experiments with plant genetics with short and long plants to prove the men contain XY chromosome and women contain XX chromosomes It is also useful to find the ownership of a child with help of the XX and XY matrix from the knowledge of blood groups It is good as long as human does not mess with it

genetics engineering and genetics is the science of understanding DNA and it's laws and changing it to have new products or a better living organism. I think man is going over what God have done...and it's a risky thing to do. Man is becoming too much ambitious to pretend doing better than God. This is my thought

Genetics is the science of genes, heridity and variations of organisms.
