left secondary
left primary
</span>
The correct answer is "right primary" or the right main bronchus. Anatomically, the right main bronchus has a larger diameter and a steeper angle (to compensate for the location of the liver). When a foreign body is accidentally aspirated, most commonly, it will lodge on the right main bronchus; especially in children.

-Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
