Question #292468
How does evolutionary forces (e.g. mutation,genetic, drift,gene,flow etc.)contribute biological variations of species at present?
Expert's answer
These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time. Genetic drift can also cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.
