The allele would be called codominant
When a dominant and recessive allele exist in an organism, only the dominant allele will be expressed. Dominant allele always mask the recessive because the gene code a protein while recessive gene doesn't. When both gene code a protein, they will be codominant and both gene will be expressed. The result could be a mixed effect. In this case, the purple is mixed color of red and blue.
 
        
             
        
        
        
<span> C.It transmits genetic information to the next generation. The key role of DNA is </span>to store genetic information for long term. It contains all components and basic structures of the cells, including RNA and proteins. They regulate how these genetic information will be expressed or transmitted.
