Answer:
3. CABD
Explanation:
The gene mapping refers to providing position to the genes on the chromosomes.  The first gene map was constructed by the Alfred Sturtevant on the basis of recombinant produces or recombination frequency which was calculated.
The gene mapping refers to providing position to the genes on the chromosomes.
In the given question to construct gene map:
1. Look for the highest recombination frequency that is 50% between the C and D.
2. Now look for second-highest value and place the gene accordingly.
3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.
Thus, Option-3 is correct.
 
        
             
        
        
        
<span>Answer: Blood leaves the left ventricle through the aorta.
The blood that is pumped from the heart and goes through all of the body structures, that need to be irrigated, leaves from the left ventricle. This ventricle will contract and push the blood to go to the aorta. From there, goes to the rest of the body.
