Question

Inbred populations have more homozygotes than hetereozygotes, which may expose deletrious alleles and eliminate favorable alleles, resulting in a reduction in fitness known as inbreeding depression. How does this affect reproductive efficiency? How does it vary among generations and family lineages?

inbreeding is when mating occurs between genetic relatives. This can that cause inbreeding depression, which is when fitness is lowered due to an elimination of favorable A wheels. So we&#x27;re going to have a lowered fitness due to favorable, favorable A wheels being lowered due to inbreeding. This will decrease reproductive efficiency so reproductive efficiency is going to decrease when an inbreeding depression occurs. However, in reading has different effects on family lineages or generations, so may actually have greater reproductive fitness from inbreeding, while there&#x27;s still experienced this inbreeding depression.

Simon Sauvageau · Answer

interbreeding is the process of meeting that occurs between genetic relatives. This process reduces hetero Zeiger frequency and increases homocide a frequency. This could be harm and this can increase arm for process of the wheels. So interbreeding is going to decrease headers I goods and increase almost I get. And this can lead to harmful recessive A leal&#x27;s and by increasing the amount of harmful recessive wheels, the overall fitness of a population will decrease. So overall fitness is going to decrease if an overall, if the overall fitness of a population decreases, the chances of survival in the population will also decrease, So interbreeding can be very harmful to a population to do this chain of events.

animal beaters sometimes utilize inbreeding, and yet they still result in healthy animals. How is this possible? How is it that inbreeding depression does not occur? So let&#x27;s remind ourselves, inbreeding is thievy mating between to genetically related organisms. So and a inbreeding depression is when there is harmful recessive a wheels that begin to increase in frequency. So the increase. So the benefit that animal breeders have is that they can choose which animals to mate so that they ensured that the harmful recess of a wheels are being selected against. So animal breeders are able to avoid this inbreeding depression by being able to choose, uh, choose meats between organisms saved like a line of dogs or camels. They&#x27;re able to see which organism may have that harmful recess of a wheel. And make sure that it does not meet with another organism or individual who has the same harmful recess of illegals. And this will make sure that the frequency of the harmful arrest recess if it wheels does not increase, and thus there&#x27;s no inbreeding depression now in the wild. Normally, if a small population in breeds for many generations, this will not occur normally, an inbreeding depression will occur. So the difference is that a wild population will have an increase in those armful recessive Leal&#x27;s if inbreeding occurs and their frequency will increase.

Look, this question is asking us about cystic fibrosis, and you will recall that cystic fibrosis is a genetic disease and that you get cystic fibrosis by inheriting to, uh, cystic fibrosis, a wheels and these air recess of Leo. No. To get cystic fibrosis, you have to have to recessive Leal&#x27;s and I&#x27;m indicating a cystic fibrosis. Julio&#x27;s ah, lower case C Um, if if you have either Sisi Capital, C Capital C or Capital C Duke Little C right, then you end up with and normal FINA type, at least with respect to cystic fibrosis. The question is asking us what would happen if you have a population where fists, cystic fibrosis with permanent and inbreeding became more common and what you need to remember. What in this case is that went inbreeding becomes common in a population. There is an increase in the number of homers I got&#x27;s and a decrease in the number of Hedorah cycles. So we would see an increase and the number of individuals who are big C, big C that is normal. Uh, and but we would also see an increase in the number of individuals who are a little see little C that is who have cystic fibrosis, and we would see a decrease in the number of individuals who are headers. I goes, that is, they have a capital C and a little CIA. Leo. All right, so in inbreeding, like individuals mate with like individuals and so individuals who say carry the cystic fibrosis alil are more likely to meet with other individuals who have the cystic fibrosis wheel. And that&#x27;s why we would end up seeing more individuals with the little see little See cystic fibrosis Pena type in a population. All right, So when inbreeding occurs, we see this increase in the number of of cystic fibrosis individuals. If there&#x27;s more who Masai goats who are little, see little C. What that means is that there are more individuals who have the disease, and if they die before they reproduce, then they&#x27;re not going to pass on the little CIA, Lille to their offspring. So if they die before they reproduce than the number of little CIA wheels in the population is going to decline. If inbreeding was extreme so that cystic fibrosis people are individuals with cystic fibrosis leaves only made it with others. This is stick fibrosis a wheels. Then eventually you could see the loss of the system. Little See cystic fibrosis olio from the population. Um, in most cases, however, there are going to be some individuals who will continue to be better is I go right and headers I got&#x27;s will continue to have that little seat polio. So in general, when inbreeding occurs, you see an increase in the number of homes. I guess individuals and you see a decrease in the number of hetero Seiken individuals. And if those homes I goats die before reproducing, there&#x27;s going to be a drop in the illegals that caused that particular disease in this case, cystic fibrosis.

this question were being asked about inbreeding and in particular, why inbreeding typically leads to a reduction in fitness. So in reading leads to reduction and fitness. And again, fitness is a measure of reproductive success. So why are inbred individuals of a population less likely to be reproductively successful on non inbred individuals? And the conventional answer, of course, And some will? Certainly, right is that you have increased levels of homos I Casady and in particular this X exposes a lot of recess. It Della teary Issa Leal&#x27;s. So remember that, uh, we have a lot of loose I chromosomes, and that&#x27;s true with other organisms as well. And most of them they have a gelateria salio the effects of that Alil is masked by a dominant A Leo, and so we never care that we have this gelateria slowly, lower. If it has an effect, it&#x27;s fact is mitigated by the presence of a dollar Leo. But remember that the hallmark of of inbreeding is that you&#x27;re going to see a greater amount of him was. I got city and a reduction of Federer&#x27;s I goats, and so you&#x27;re going to expose these recess of a Leal&#x27;s And of course, if you have a lot of them, you&#x27;re going to see a reduction fitness. It&#x27;s just sort of a natural consequence of of having poorly functioning on wheels running the show. So the conventional answer is that inbreeding, these reduction of fitness because of this, this increase in the effect of Gelateria Soleil&#x27;s.

hi, everyone. So, first question, we need to know the definition. Um, inbreeding is basically when related individuals meet and, well, we got down. So when related individuals made as you may assume, there&#x27;s a lot of negative effects. So basically what happens is you haven&#x27;t increase in Homo psych. It&#x27;s oh, which are similar. So there&#x27;s less diversity, for example, and then you have a decrease in hetero cycle. It&#x27;s and this is important to note, likely much earlier, because in as a result, last diversity. Also, it can be dangerous, as you can have unintended consequences in your offspring, as in a lot of mutations and people treats that you don&#x27;t want their, um, but another thing that happens is that you move away from the Hardy Weinberg equilibrium, and so that cut population is no longer following that equation. Um, and so, yeah, it is positive sort of meeting. So increased relatedness. When you meet with related individuals. Thanks
