. If gametes from a gene pool combine randomly to make only a small number of zygotes, the allele frequencies among the zygotes may be different than they were in the gene pool because:

a).The effects of natural selection are more pronounced in small populations.

b).The effects of genetic drift over several generations are more pronounced with small numbers of gametes.

c)The effects of differences in frequencies for different alleles are more pronounced with small numbers of zygotes.

d). The effects of sampling error are more pronounced with small samples.

Solution

Because of the effects of sampling error are more pronounced with small samples. If at all there is random genetic drift which is only force operating within a population, all loci will be fixed or become single allelle. And without a reserve genetic variation, a population will be unable to respond genetically to changing environmental conditions. The reason for small population sizes in species that are threatened or endangered are of concern. Thus, allele frequencies are different than they are in gene pool.
