The molecular biology technique of reverse genetics can be useful for determining the function of a gene.
<h3>What is reverse genetics?</h3>
Reverse genetics is method use in molecular biology to determine gene function in an organism 
The procedure in reverse genetics involves modifying or certain nucleotide sequences in the DNA coding for a functional gene and then observing changes to the phenotype of the organism brought about by the modifications. 
Therefore, reverse genetics can be useful for determining the function of a gene.

Normal polarity
Explanation:
Earth's magnetic field used to be twice as strong 1.5 billion years ago as it is today and Earth's temperature other than what the geologists see from the 'normal' pattern. It has been noticed that some volcanic rocks were magnetized in opposite direction to the direction of the local Earth's field. It is clear that the Earth has experienced the normal polarity 1.5 years ago but at that time, the Earth's polarity was poorly understood.
 
        
             
        
        
        
Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits. A single gene is responsible for pigmentation and hearing.
