In a population, what is the consequence of inbreeding? Does inbreeding change allele frequencies? What is the effect of inbreeding with regard to rare recessive alleles in a population?

Question

Accepted Answer

Hello, everyone and welcome to today's video. So which of the following processes in our population can lead to changes in the genotype frequencies but does not directly change the ally of frequencies. As answer to is A, we have the bottleneck effect. B is natural selection C is inbreeding. D is the founder effect. Now, let's begin by analyzing A which is the bottleneck effect. This is where a drastic event is going to greatly reduce D A leo frequencies of a population. And because the all frequencies are being reduced, this is definitely going to change them. So we're going to cancel it out because remember that we're looking for something that does not directly change the all frequencies. Let's move on to B which is natural selection. Remember that natural selection is a process that is going to favor individuals that have better fitness in our population. So let's say that this fitness is created by a specific A leo if these individuals are favored, that means that they're going to be able to pass on their traits more often than not into the future population, which is going to increase that, that Ali's frequency in the population because of this natural selection is also going to change the ali frequencies of the population and we're going to cancel it up, then we have D which is the founder effect. Well, remember that the founder effect is a type of genetic drift. And during the founder effect, a very small portion of an original population is going to separate and form a colony. But since we only took a very small part of the original population, that means that we left out many a or just we did not get as much of a great representation of the population as we hoped in most cases. And because of this, this new colony is going to have a reduce a frequency and it is going to be missing many of the all that the original population had. And so this is definitely going to reduce the frequency, change them. And we're going to because of that cancel out the founder effect. Finally, we have see which is going to be inbreeding. Remember that inbreeding relates to meeting with people that are people or just organisms that are related to you. And because of this, there is no, there is not going to be an introduction of new all into this population. We're going to be keeping the allele frequencies the same because we're mating with organisms that are related. And because of this answer choice c in breeding is the correct answer for this question. It will change genotype frequencies, but it does not change the idea of frequencies of a population. I really hope this helped and I hope to see you on the next one.
