Together with ____, ____ provide(s) for genetic variability within species and, ultimately, the evolution of new species.

Question

Quizplus · Accepted Answer

Recombination and mutations both provide for genetic variability within species and can ultimately lead to the evolution of new species. Recombination, which occurs during sexual reproduction, shuffles and combines genetic information from two individuals, creating new combinations of alleles. Mutations are changes in the DNA sequence that can arise spontaneously or be induced by a variety of factors, and can create new alleles or alter existing ones. Together, these processes introduce genetic diversity within populations, which is the raw material for natural selection and evolutionary change. The other answer choices are incorrect because they either do not involve genetic variability (DNA repair) or are not directly involved in creating new genetic information (DNA glycosylase).
