A chicken breeder has a population of chickens where the average number of eggs laid per hen per month is 34. The narrow-sense heritability is 0.75. With this information is it likely that a breeder could select for an increase in eggs per hen laid each month?

Yes, because the narrow-sense heritability is 0.75, this means selection is likely to occur

Okay. So this question says that there's a chicken breeder, and he has some chickens, obviously, and it says, the average number of eggs laid per hen per month is 34. So every hen that he has, there's an average number of 34 eggs laid per month. Says he calculated the narrow sense heritability, which remember is lowercaseh 0.75, and says, okay, with this information, he's interested in whether he would be able to breed chickens to increase the eggs laid per hen per month. So with the this narrow using this information, is it likely that he would be able to breed for increased egg production in chickens? So a says, no, breeders never know whether they can select for a trait, which is unlikely. Right? We know breeders have a way to be able to select for a trait, and that way is narrow since irritability. But with this number, we need to figure out whether it's likely or not. Says, no. He won't because you have to use the broad sense irritability to determine whether selection could cause an increase in eggs or yes, that this value means selection is likely to occur. So when breeders, are trying to select for a trait, figure out if they can breed to increase that trait, They do use narrow sense heritability, so can't be right, so the answer here is The narrow sense heritability is point 75, which means it's close to 1. And that means that it is very likely that a breeder would be able to select pins to be able to breed them to increase egg production. So with that, let's move on.
