B) recessive alleles
C) phenorype
D) genotype
Correct Answer: C
Solution :
Natural selection is the process by which traits become more or less common in a population due consistent effects upon the survival or reproduction of their bearers. It is a key mechanism of evolution. Natural selection acts at die phenotype or the observable efcaaceristics of an organism, but the genetic heriTable) basis of any phenotype which gives a reproductive advantage will become more common in a population. Over time, this process can result in adaptations that specialize populations for particular ecological niches and may eventually result in the emergence of new species. In other words, natural selection is an important process (though not the only process) by which evolution takes place within a population of organisms. As opposed to artificial selection, in which humans favour specific traits, b natural selection the environment acts as a sieve through which only certain variations can pass.
