Answer:

genetic drift

Explanation:

The newly isolated population of beetle would have very different allele frequencies than the main population because of <u>genetic drift.</u>

Genetic drift refers to<u> a change in the frequencies of alleles in a population over generations brought about by pure chance</u>. Genetic drift can cause a bottleneck or founder effect. A <u>bottleneck effect</u> is a temporary decrease in the genetic diversity of a population while the<u> founder effect</u> refers to a decrease in the genetic variability of a new population formed from a small number of individuals that get separated from a larger population.  

<em>Hence, the newly formed population of beetles would have lower allele frequencies than the main population due to the founder effect brought about by genetic drift. </em>

1. What is the continental shelf? What is the subtidal zone?
Natalka [10]

Answer:

Continental shelf - the territory of seabed around an enormous landmass where the ocean is moderately shallow contrasted and the untamed sea. The mainland rack is topographically part of the mainland hull.

Subtidal Zone- Where the water is generally liberated from suspended particles, daylight can enter the water surface to a profundity of more than 100 feet. Shallow subtidal networks in this photosynthetic zone might be ruled by thick collections of kelp in certain zones.
