Answer:
Natural Selection
Explanation:
Genetic variations are one of the most important factors in the evolution of organisms. Mutations are fundamental in this process. When a mutation is produced in an organism, and that mutation produces an 'attractive' trait that will potentially help the organism to reproduce, then, this trait (if the mutation is hereditary) will be passed on to the subsequent generations and will stay in the population as it is beneficial.
This perfectly illustrates natural selection, which refers to a process in which a trait that is advantageous will stay in a given species if it helps the individual to survive and reproduce. In other words, nature "selects" the organisms that possess the 'best' traits so they can pass them from generation to generation and increase their chances of survival.

Answer/Explanation:
Sexual reproduction is a a combination of chromosomes from each mate. Since each mate has different pairs, when combined they produce a completely different product.
This product has half of the characteristics from both sides.
Below is an example of how this works. The bold cells are from one mate and the other is from the other.
X ---> >< <--- X
X ---> >< <--- X
X ---> >< <--- X
X ---> >< <--- X
X ---> >< <--- X
As shown, the cells broke in half and combined with the other half forming a cell of 50/50. With this process it never created an identical offspring but different ones each time since different parts of the cell combines in different ways but still remains half of one and half of the other.
