Answer:
Genetic drift
Explanation:
Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.
In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.

Answer: they are distinguished from one another <span>by the number of fatty acids attached to the glycerol backbone.
</span>
<span>A monoglyceride is a molecule formed by a glycerol backbone and one
fatty acid covalently bonded to it through ester linkages.
</span>A diglyceride is a molecule formed by a glycerol backbone and two fatty acid chains covalently bonded to it through ester linkages.
A tryglyceride is a molecule formed by a glycerol backbone and three fatty
acid chains covalently bonded to it through ester linkages.
The answer to this question would be: coconut oil and dairy.
