Answer:
<em>They will have a large number of genetic variations.</em>
Explanation:
Genetic variations arise due to sexual reproduction or due to the process of meiosis.  
Cross-pollination can be described as a process in which the pollen of one flower is transferred to another flower. The pollen when fertilizes the egg in the stigma, will produce offspring with varied genetic characteristics. This will be because the pollen would carry the trait of another flower and the egg of another flower. This will lead to many genetic variations. 
 
        
             
        
        
        
Well basically it shows the genetic history of a group of related individuals.
