The explanation for the question is in the"Hardy-Weinberg principle" pdf attached below.
 
        
             
        
        
        
Our planet has so many different ecosystems in which species live in. Whether it is the rainforest or a desert region, it seems that almost any place on earth can be one in which species have learned to adapt to living there. In short, yes there is great diversity on this planet. 
        
                    
             
        
        
        
Incomplete dominance is when one allele is not completely dominant over the other (blend in), and codominance is when both alleles affect the phenotype(appearance)
Example of incomplete dominance: a red flower mates with a with flower and makes an pink offspring
Example of codominance: a brown cow mates with a with cow and the offspring being with and brown polkadots
