Genetics

Genetics is a branch of biology that involves the study of heredity and variation in living organisms. Tracing its roots as a field of study to Gergor Mendel, the Augustinian priest whose 19th century experiments on pea plants introduced the world to the laws of inheritance, genetics today plays an increasingly important role in the plant and animal breeding industries around the world. Whether you're interested in planting genetically engineered corn seeds or selectively breeding ball pythons, a basic understanding of genetics sure can't hurt. For that reason, as part time snake breeders, we've tried to pull together a comprehensive overview of the world of genetics - from mendelian inheritance to the application of genetics in the animal breeding industry, we've tried to touch on a little
bit of everything. Hopefully some of it will be useful.
