1. Mendel conducted an experiment with many different types of peas. He cross-bred these different species of peas with each other and discovered that their offspring would have traits resembling one of their parents. As more peas are cross-bred, more traits of different peas appeared significantly in future offspring. The pea experiment by Mendal divided heritable traits into 2 categories, one being blendable and ephemeral and the other heritable and lasting for a long period of time.
2. The structure of the DNA was discovered by James Watson and Francis Crick. It is in the shape of a double-helix
3. Variations causing mutation can be caused by: a single letter replaced in the DNA strand, a string of letters gone, duplication or addition of new letters, and transformation of the originial letters.
4. Evo-devo: The study of the effects of mutation in developing genes and its role in the process of evolution.
5. A child born from parents that does not drink milk after their infancy does not have the lactase enzyme to digest milk through adulthood, therefore they are lactose intolerant. However, a child from a family that does drink milk after infancy will be lactose tolerant.
