One thing that us perceive the details of a tactile stimulus is in the somatosensory cortex, which refers to the fact that the cortex has greater representation of those regions of the body that provide better acuity, and thus better information about detail.

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
