Microevolution can be said to have taken place when a. a population experiences a shift in allele frequencies. b. a feature of a
n individual animal changes through use or disuse. c. a mutation occurs in a population. d. several mutations occur in a population. e. when a population has different forms of the same gene.
A genetic draft changes in allele frequencies in a populace from age to age that happens because of chance occasions. To be increasingly accurate, genetic drift is changed because of "examining blunder" in choosing the alleles for the cutting edge from the genetic stock of the present age. Albeit drift occurs in population all things considered, its belongings will, in general, be more grounded in little population
Hence, the right answer is option a " a population experience a shift in allele frequencies"
