As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).
How
often an allele occurs in the gene pool is allele frequency.
<span>Allele
frequency defines how common an allele is in a population. It can be calculated
by counting how many times the allele appears in the population and then
dividing by the total number of copies of the gene.</span>
