definitionevolution on the smallest scale—generation to generation change in the frequencies of alleles within a populationchoose an answer1 macroevolution2 genetic drift4 adaptation5 microevolutiondont know?

Explanation:

The definition describes small-scale, generation-to-generation allele frequency shifts in a population, which matches the core of microevolution. Macroevolution refers to large-scale evolutionary changes above the species level, genetic drift is a mechanism of evolution, and adaptation is a result of evolutionary processes.

Answer:

1. Microevolution
