Chemical (mutagens)
usually either mimic the structure of nucleotides and are inserted in DNA or either cause
chemical changes  (such as alkylation) in nucleotides hence causing mismatching during replication.
Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an
increased likelihood of mutations during the repair of the DNA by cell
mechanisms. 
 
        
             
        
        
        
Preventing wind erosion in a dry, sandy area is feasible through any of the following land-use practices:
a. Tillage - creates soil roughness by making furrows and ridges that are perpendicular to the direction of the wind. 
b. Crop rotation - rotations of legumes followed by shrubs followed by trees then back to legumes work best.
c. Intercropping - is the most widely used particularly in countries with desert areas. One of the most popularly used is oasis agriculture that makes use of about 3 layers of vegetation. 
        
             
        
        
        
Answer:
The frequency of the recessive allele which codes for grey pelt character will rise above 20%, while the that of the dominant allele that confers brown pelt character will decrease below 80%.
Explanation:
Since the population of foxes with brown pelts are being selectively hunted by humans, the population of foxes with brown pelts will keep reducing while the population of foxes with grey pelt will thrive in its place.
<em>Hence, the the frequency of the recessive allele which confers grey pelt attribute will rise above original 20% within the population, while the dominant allele will decrease below 80%.</em>
