<span>vegetative propagation.
Budding and grafting. It is mainly used for propagating a plant. In layering sometimes the portion of the aerial stem grows roots while it is still attached to the main plant and then it is separated from the main plant and allowed to grow on its own. This is another technique used for layering. </span>
        
             
        
        
        
Answer:
The correct answer is given below:
Explanation:
Depending upon the availability of oxygen, pyruvic acid follows, a variety of metabolic pathways.  
In the absence of oxygen or under anaerobic conditions, the pyruvic acid further metabolised into one of three pathways: lactic acid fermentation, alcohol fermentation and cellular anaerobic respiration. During fermentation or anaerobic respiration 2 ATP is produced.  
In the presence of oxygen or under aerobic conditions, the pyruvic acid completely oxidised to carbon dioxide, water and 38 ATP.  
 
        
             
        
        
        
The genotype would be X'Y for the father (he would be colorblind)
The genotype would be X'X for the mother (she would be a carrier)
The offspring would be X'X' _ X'X_ X'Y_ XY
The ratio would be 1:1 normal to colorblind

DNA/fingerprints are all unique, therefor it is easy to match a fingerprint to a person thus they use this mechanism in criminal investigations because only one person woul have matching DNA to the prints on the scene, and that is the criminal.
Hope this helps :)
