The correct genotypes of the parents are ggrr for yellow pods with wrinkled seeds and GgRr for <span>heterozygous for green pods with round seeds.
If the heterozygous individuals for both traits express have green pods and round seeds that tells us that these traits are dominant.
In the gross presented below, you can see that the offspring will have 4 different genotypes, all present in an equal percentage:
</span><span>gGrR 25% 
</span><span>gGrr  </span>25% 
<span>ggrR 25%
</span><span>ggrr 25%</span>
 
        
        
        
Answer:
D
Explanation:
Relative Age Determination. Superposition of rock units is a very simple and straightforward method of relative age determination. The principle states that in a sequence of undeformed sedimentary rocks the oldest beds are at the bottom and the youngest ones are at the top.
 
        
                    
             
        
        
        
Stanley Miller's experiments showed a pre-cellular life could have begun with the formation of lipids, but it should be noted that this is not necessarily true.
