Answer:
Genetic drift
Explanation:
Based on the information given here, the observed genetic variation is most likely an example of Genetic drift .
Genetic drift is the variation in the relative frequency of different genotypes in a small population, owing to the change disappearance of particular group of genes as individuals die out do not reproduce.
The above mentioned information indicate a typical example of Genetic drift
1. Genetic engineering (bioengineering)
2. Cloning
3. Stem Cell research
4. GMO production
To name a few
Absorption is the correct answer
