Genetics is the branch of biology that looks at how parents pass traits on to their offspring. It all started more than 150 years ago when a monk named Gregor Mendel conducted breeding experiments with pea plants that led him to discover the fundamental rules of inheritance. Although, Mendel worked with peas. His ideas explain a lot why you look and function the way you do.
Dogs have puppies, hens have chickens and your parents had you. What do all three sets of parents have in common?. They all passed their traits on to their offspring. Traits that are inherited from one generation to the next are called heritable traits. When living things reproduce, they make copies of their DNA. the DNA is the genetic code for the traits of organism, which means the parent's blue print. Of course, in sexually reproducing species, offspring aren't exactly like their parent for several reasons.
- Offspring receive half of their genetic information from their father and half from their mother.
- Even heritable characteristic can change slighty.
- Some traits are acquired rather than inherited.
- Some inherited traits are affected by the environment.
