Discuss: Which is more likely to result in the fixation of a new trait in a population? The force of Natural Selection The force of Artificial Selection

Solution

Answer: a) natural selection

The fixation of allele in a gene pool is mainly due to the driving force i.e. natural selection, whereas in the absence of mutation, the allele will be fixed but two variants are not going to be fixed within the population. Only one allele remains fixed and in case, alleles are neutral for fixation so that, the fixation probability i snot going to change with allelic frequency due to no chance of \"occurrence of mutation\"
