The answer to the biology question being presented above would be 'sexual reproduction'. Genetic variability is the most important result of sexual reproduction. In this variability, the genes are varied through sexual union and reproduction.

I would say sexual selection
If you have options though I would feel more confident giving you my answer, if not, that's fine too.
Hope this helps :)
 
        
                    
             
        
        
        
Genetic Diversity because someone can be the same species as you but they might look different because of their parents. The genes from the parents go to the kid.
        
                    
             
        
        
        
Mercury's seasons are difficult to determine. This is because it has virtually no tilt (0.03 degrees), but a highly elliptic orbit. ... Mercury also has a bizarre rotation, spinning three times (every 53 Earth days) over two rotations around the Sun, making it impossible to tell when one season begins and one ends.
