Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism?
2. Chromosomal aberrations
3. Genetic drift
4. Recombination
Variation in gene frequencies within populations can occur by chance rather than by natural selection.
This is referred to as:
1. Genetic drift
2. Random mating
3. Genetic load
4. Genetic flow
