Answer:
They can use a technique called Polymerase Chain Reaction. This can be done in a test tube or even in a organism. It usually relies on something called  Thermostable DNA Polymerase and Taq polymerase. It requires DNA primers that is designed specifically for that DNA region (interest).

The results of the punnet square show that one out of 16 offsprings will have both the qualities of having terminal flowers and being a dwarf. 
A punnet square can be described as a diagram which depicts the likely outcomes of a cross. In the above punnett square, for the plants to have both terminal flowers and to be dwarf, both the alleles should be recessive for the traits. 
 
        
             
        
        
        
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
•	Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
•	Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
