the patial vapour pressure of any volatile componants of a solution is equal to the vapour pressure of the pure components multiplied by its mole fraction in the solution
Random genetic drift in a population probably results from -
Large population size
Constant low mutation rate
Highly genetically variable individuals
Interbreeding within small population
Interbreeding is the act of mixing different species or varieties of animals or plants and thus to produce hybrids. This hybrid act as a major source of genetic drift.
