Microevolution can be described as ____.Group of answer choicesThe successful interaction between an organism and the environmentThe blending of acquired characteristics from one generation to the nextA change in allele frequencies from one generation to the nextThe differences that exist between individuals or populations of the same speciesNone of the above
Solution
Microevolution can be described as a change in allele frequencies from one generation to the next.
Here's a step-by-step explanation:
-
Microevolution refers to small-scale changes in gene frequencies in a population over a few generations. These changes can be due to several processes: mutation, gene flow, genetic drift, and natural selection.
-
An allele is a variant form of a gene. Each individual has two alleles for each gene - one from the mother and one from the father.
-
The frequency of an allele refers to how common that allele is in the population.
-
Therefore, a change in allele frequencies from one generation to the next means that the commonness of certain gene variants in the population is changing. This is the essence of microevolution.
