At which level does 'genetic evolution' occur (at which level do we measure it or assess whether or not it has happened)?

Question

Quizplus · Accepted Answer

Genetic evolution occurs at the population level, as it involves changes in the frequency of alleles in a population over time. It is not measured at the interspecies or habitat level, as those involve different species or environments. While genetic changes can occur at the individual level, it is not considered genetic evolution unless those changes are passed on to future generations and impact the population as a whole. The chromosomal level refers to changes in the structure or number of chromosomes, which can be a factor in genetic evolution but is not the primary level at which it occurs.
