The answer is; 
- The recombination frequency is proportional to the distance between the two genes
- The lower the recombination frequency, the farther apart two genes are on the chromosome 
Genes that are close together are more likely to be passed together to offspring during recombination. Geneticist compares the ration between the proposed phenotype offspring and actual phenotype offerings in a population. The higher the recombination frequency (centimorgans," or cM), the closer the genes are linked together, physically. 
 
        
             
        
        
        
Explanation:
Body cells make up the body of any multicellular organism. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.

Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.
