Explanation:
When you make the cross. You get
HH HH Hh Hh. 
So the genotypic ratio - 2:2 which is also 1:1.
The phenotypic ratio - 4. Since Hh and HH are horned organisms. So they only differ in their genotypic make up. 
 
        
             
        
        
        
The answer would be you bounce a basketball
        
             
        
        
        
Plant A would have one allele from each parent, so the leaf color will be the dominant one.
Plant B would have a more complex percentage for traits. And it'll probably "cancel-out" some alleles only showing the info given in one of them.
