Mendel and genetics

• Gregor Mendel carried out breeding experiments on pea plants and recorded which characteristics were inherited
• Mendel said characteristics are determined by inherited ‘units’ (aka genes) and the ‘units‘ (aka genes) don't change when passed down.

  Mendel also showed that some characteristics can be masked and reappear in later generations (recessive alleles)
• Mendel wasn't believed by scientists because there was lack of knowledge on DNA and there was no technology
