During sympatric speciationA) evolution occurs at a very rapid rate.B) phenotypic differences disappear between subpopulations.C) reproductive isolation between subpopulations occurs without geographic isolation.D) a geographic separation occurs between certain subpopulations which leads to reproductive isolation.E) mutation rates are unusually high, leading to reproductive isolation between two subpopulations.

Question

During sympatric speciationA)  evolution occurs at a very rapid rate.B)  phenotypic differences disappear between subpopulations.C)  reproductive isolation between subpopulations occurs without geographic isolation.D)  a geographic separation occurs between certain subpopulations which leads to reproductive isolation.E)  mutation rates are unusually high, leading to reproductive isolation between two subpopulations.

PHYSIQUE CHIEF · Accepted Answer

Final Answer : C, Explanation :  Sympatric speciation occurs when reproductive isolation happens within a population without any physical separation. This can potentially happen due to a variety of factors, such as differences in mating behavior, niche specialization, or polyploidy. However, it does not necessarily entail a rapid rate of evolution or the disappearance of phenotypic differences between subpopulations.
