Question

Quizplus · Accepted Answer

Natural selection operates on phenotypes, but it does not ensure that only dominant alleles, only beneficial alleles, or new traits caused by environmental stresses are passed on to the next generation. All alleles, including recessive and neutral ones, can be passed on, and acquired characteristics are not inherited according to the principles of genetics.
