The bottleneck effect is used to describe an event where a population decreases. One example involves the northern elephant seal

. They have a reduced genetic variation due to a population bottleneck humans inflicted on them in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted. Which phrase best explains this change if gene frequency?

I think the best phrase to describe this would be Founder effects. Founder effects occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have; a non-random sample of genes in the original population. Reduced variation from the original population.. According to Bottlenecks and founder effects, genetic drift can cause big losses of genetic variation for small populations.

Ainat [17]

The physiological basis for having your daughter continue is through the way she moves in which up until now, she hasn’t been moving smoothly like other child but rather than awkward. Through this, the mother would likely think that she should let her daughter drop out from that class because she doesn’t seem to have any improvement and if she were to have an improvement with her movements, then the mother would likely let her daughter to continue.
