Genetic diversity
Explanation:
Sexual reproductions, mutation, and crossing-over generates a wide range of genetic diversity within a population. 
- Sexual reproduction is a type of reproduction in which gametes fuses to produce a fertile and viable offspring. 
- Mutation is the process of altering genetic sequences in population to production new breeds called mutants. 
- Crossing-over is the exchange of chromosomes between two homologous pairs. 
All these processes ensures that a pool of diverse gene exists within a population in order give competitive and adaptability advantage to organisms.

I think the correct answer from the choices listed above is option A. The relationship between the themes of “place” and “human-environment interaction” is that the characteristics <span>of “place” include things like economic activity, architecture, and culture, all of which are human elements that alter or can be influenced by the environment. </span>
        
                    
             
        
        
        
Answer:
Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).
