Consider the following claims. i. Inherited genetic variations are caused by genetics only. They are caused by crossing over and assortment in the development of sex cells in meiosis. The random joining of sex cells can also be a source of genetic variation. Mutations also cause variations in genetic sequences. Mutations are always harmful.
ii. Inherited genetic variations are caused and influenced by environmental factors only. Factors like an organism’s habitat conditions and behavior can affect variation within a population.
b) Think about what these claims are saying. Determine if you support these claims. If you support these claims, do you support the totality of the claims or just parts of the claims?
