Under natural conditions, which of the following may cause allele frequencies to change? A. Limited resources, which could cause
one allele to have an advantage B. A random assortment of alleles during sexual reproduction C. No emigration from the population D. No immigration into the population
The<span>
answer is A. Limited resources will
result in stiff competition among
individuals in the population. This will
result in differential
survival across the population because only
the individuals that are able to outcompete
the others will be able to reproduce and pass their genes to the next
generation. This, therefore, will change the allelic
frequency of the <span>population.</span></span>
