Final answer:
Sexual reproduction causes offspring to show variation from the parents due to the mixing of genetic material from two parents.
Step-by-step explanation:
In sexual reproduction, the offspring show variation from the parents.
This is because sexual reproduction involves the fusion of gametes from two parents, resulting in a mixing of genetic material and the creation of unique combinations of genes.
For example, in humans, each offspring inherits half of its genetic material from the mother and half from the father, leading to diverse traits and characteristics.
