Genetic drift in a small population for multiple generations can significantly affect the composition of a population’s gene pool. Following some observation are given for reason of Genetic drift?
A) Small populations are threatened by a loss of genetic variability. This loss may be caused by inbreeding, genetic drift, and limited mating.
B) Sampling error can arise is through the founder effect, which is due to the limited matting within population
C) Genetic drift arises is through a genetic bottleneck, which develops when a population undergoes a drastic reduction in population size.
D) Variance in allele frequency due to genetic drift will be maximal when one allele is very rare and the population size is small.
Which of the above observation are true?
