Answer:
Since sexual reproduction needs two individual animals for it to occur and genes from both, the offspring won’t be exactly like one or the other parent, so, on a larger scale, we will all be unique and diverse.
For further understanding, let’s think of an example. Your dad and mom are different than you are because you are created from both of their genes combined, creating a unique you. This promotes diversity for that we are all unique.
I hope this helps! :)
