Form atoms to traits

1.) Mendel was important because he helped adjust and prove Darwin's theory. By crossbreeding pea plants, he was able to prove that the offspring did indeed share similar traits. He also proved that heritable variations are their own separate entities that are always passed on but not always present.

2.) DNA:

Discovered by James D. Watson and Francis Crick. 

3.) 1. Copying errors during DNA replication such as copying the wrong letter of skipping a letter.

2. Substitution of different strands of DNA can cause mutations, and can change the variation.

3. Point mutation is when a single base pair changes for example muscle growth in dogs such as the whippet.

4. Insertion is when a base pair sequence is inserted into a gene that can cause different traits to become present. For example wether pea plant seeds are wrinkled or not.

5. Gene copy number is when duplicating errors occur in cell division leading to variations in a species. For example, humans look very different from each other but we are all the same species.

4.) evo-devo is the study of the effects of changes in important developmental genes and the role they play in evolution.

5.) lactose intolerance into adult hood can be traced back to the genes of our ancestors. In Africa the ability to digest milk was useless because of milks lack of abundance. However, when our ancestors reached Europe, they began to herd milk producing animals that made the gene of lactose tolerance more prominent.
