The answer would be a Geologist.
        
             
        
        
        
Genotype is the entire set of genes inherited by and heredity is the observable properties that come from genetics
        
             
        
        
        
If there is no oxygen , the cells go through anaerobic respiration which leads tot he build of lactic acid in the muscles. This is why we get sore and feel the burn during a workout. 
        
             
        
        
        
That population will have less variability in size which has slower rate of mutation or has experience less mutation.
<h2>What is mutation? </h2>
A mutation refers to a change in a DNA sequence of an organism. Mutations can result from DNA copying mistakes that is made during cell division, exposure to radiation or chemicals which is called mutagens, or infection caused by viruses.
If mutation occurs slowly or not completed, it will leads to less variability in size so we can conclude that the population will have less variability in size has experience less mutation.
