2. The samples must be independent.
3. Each population must have a normal distribution.

Which of the following are responsible for the differences between species and for differences between individuals in the same population?
Genetic variations, which arise from mutations and recombination of genetic material during reproduction, are responsible for the differences between species and between individuals in the same population. These variations can lead to differences in physical traits, behaviors, and other characteristics among organisms. Additionally, environmental factors can influence the expression of these genetic differences, leading to further diversity within and between populations.
