WebMutations create new alleles and increase genetic variability. Most mutations do not cause significant changes to the health or functioning of an organism. However, if a mutation reduces the chances of survival, the organism may die before reproducing. Therefore, such harmful mutations are likely to be eliminated by natural selection. WebFirst, natural selection is not all-powerful; it does not produce perfection. If your genes are “good enough,” you’ll get some offspring into the next generation — you don’t have to be perfect. This is apparent in the populations around us: people may have genes for genetic diseases, plants may not have the genes to survive a drought ...
