Select the forces that promote variation
WebThese forces all influence the patterns and amounts of genetic variation in natural populations in different ways. Mutation increases genetic variation. Random genetic drift reduces genetic variation. Selection typically reduces variation. However, some forms of selection can maintain genetic variation. For example, frequency dependent or

Webcontribution per unit = MSP – variable costs (VC) BEP = $200,000 ÷ ($15 – $7) = $200,000 ÷ $8 = 25,000 units to break even. To determine the breakeven point in dollars, you simply multiply the number of units to break even by the MSP. In this case, the BEP in dollars would be 25,000 units times $15, or $375,000. http://ibgwww.colorado.edu/~carey/p4102dir/bookchaptersdir/five.forces.pdf
