Which is a criticism of sympatric speciation?  A.) many cases of sympatric speciation are actually microallopatry B.) allopatric speciation is less common and scientists should focus more attention on locating additional examples C.) sympatric speciation is only associated with changes in ploidy, a process so rare that it's relatively unimportant D.) since most examples of sympatric speciation involve post zygotic isolation, hybridization nearly always results in their reversal

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
