Which statement is correct about a bottleneck event?

A. A bottleneck event decreases the population of a species permanently.

B. A bottleneck event decreases the gene pool of a population.

C. A bottleneck event increases the gene pool of a population.

D. A bottleneck event increases the population of a species permanently.

Answers for 2022 connects Traits, Survival, and Reproduction Quick check are:

1) A bottleneck event decreases the gene pool of a population
2) inbreeding
3) It has temporarily decreased, so disadvantageous traits are more likely to be passed on.
4) the level of genetic variation in the population
Your welcome :)

OMG THANK YOU @space boy !! ITS ACTUALLY RIGHT

Well, looks like we have some options to wiggle through. Let's put on our thinking cap and clown shoes to find the answer!

A. A bottleneck event decreases the population of a species permanently. Hmm, that sounds like a sad circus act. Life under the big top can be tough, but a bottleneck event doesn't necessarily mean curtains for a species forever. So, this option is not quite right.

B. A bottleneck event decreases the gene pool of a population. Ah, genetic shenanigans! When a bottleneck event occurs, it often leads to a reduction in the diversity of a population's gene pool. So, this statement seems to be on the right track, but let's see if there's a better answer.

C. A bottleneck event increases the gene pool of a population. Oh, dear, this is like a clown getting stuck in a tiny car. A bottleneck event actually leads to a decrease in gene pool diversity, not an increase. So, this option is out of the running.

D. A bottleneck event increases the population of a species permanently. Well, if only that were true, we'd have overflowing clown cars everywhere! Unfortunately, a bottleneck event typically results in a decrease in population size, not an increase. So, this option is not quite right either.

So, after juggling the options around, it seems like the correct answer is:

B. A bottleneck event decreases the gene pool of a population.

Remember, a little reduction in gene pool diversity doesn't have to be a big top disaster. Populations have their ways of bouncing back!

The correct statement about a bottleneck event is:

B. A bottleneck event decreases the gene pool of a population.

To determine which statement is correct about a bottleneck event, let's first understand what a bottleneck event is.

In biology, a bottleneck event refers to a sudden and significant reduction in the size of a population. This reduction can occur due to various factors such as natural disasters, disease outbreaks, or human activities.

Now, let's evaluate each statement:

A. "A bottleneck event decreases the population of a species permanently." This statement is partially correct. A bottleneck event does cause a decrease in the population, but it doesn't necessarily mean the decrease is permanent. If the population recovers and returns to its previous size or expands beyond it, then the decrease is not permanent.

B. "A bottleneck event decreases the gene pool of a population." This statement is correct. When a population goes through a bottleneck event, the smaller group that remains will have reduced genetic diversity compared to the original population. This reduction in genetic diversity is referred to as a decrease in the gene pool.

C. "A bottleneck event increases the gene pool of a population." This statement is incorrect. A bottleneck event actually decreases the gene pool of a population, as mentioned in the previous statement. This is because the individuals that survive the event carry only a subset of the original population's genetic diversity.

D. "A bottleneck event increases the population of a species permanently." This statement is incorrect. A bottleneck event generally leads to a decrease in the population size, not an increase. It's important to note that the decrease in population size can have both short-term and long-term effects, depending on various factors like the severity of the bottleneck and the population's ability to recover.

Based on the explanations above, the correct statement about a bottleneck event is:

B. A bottleneck event decreases the gene pool of a population.
