Accepted Answer

Hi, everyone. Let's look at our next question. It says cystic fibrosis is an example of an autism or recessive genetic disorder. If an affected male, little R, little R marries an unaffected female, big R big R, how will it affect their offspring? Well, in this case, we have a cross between a homos, I guess recessive individual and a homocide is dominant individual. Since each individual can only pass on one type of value, one will always pass the recessive allele, one will always pass the dominant allele 100% of the offspring in this case will be heterocyclic, they will all be big R, little R and in the case of a recessive genetic disorder, that means they'll all be carriers but not affected by the disorder. So with that in mind, let's look at our answer. Choices. Choice A says all their offspring will get affected, but that's not correct. Their offspring, none of them will actually be affected by the disease because that requires being home as I guess, recessive. So we'll cross that out because that would mean little R, little R which none of them are. Choice. B says all their offspring will be homos, I guess for the recessive trait for the same reason. That's not our answer because that would mean their genotype would be little r, little R choice C says the disease will not emerge in the next generations. Well, here, the key is that we've got generations plural. We will not see the disease emerge in the next generation. Singular. The offspring of this particular couple, they will just be carriers but they being carriers. You could see this in further generations as if any of their Children have offspring with someone who carries a recessive gene. They could have Children, grandchildren. The original couple could have grandchildren, great grandchildren, great, great grandchildren affected by the disease. So choice C is not correct. So we're down to choice d all their offspring will be carriers which we know is our correct answer. See you in the next video.
