Explain why a 50 percent recovery of single-crossover products is the upper limit, even when crossing over always occurs between two linked genes?

Video transcript

Hello everyone and welcome to today's video. So what is the structure that is foreign between diets during closing over? Let's go over each of our answer choices so that we may solve the problem. Beginning by answer choice A we have etcetera. Well, I want you to recall from previous videos that is going to be describing for paired chroma tips because of this. This is an incorrect answer choice and we're going to cancel it out. Then we have by violence and by violence is going to be describing a pair of homologous chromosomes. This is why it has this prefix by here. This is not the answer choice that we're looking for. So we're going to cancel it out. Then we have sister chromosomes and sister chromosomes are going to be the actual pairs Or just two copies of the same chromosome. None of these are going to be the structure that is formed between the diets and closing over. So we're going to cancel all of them out. And finally we have kai as maatta and maatta is the only remaining answer choice and it is in fact the structure that is formed between diets during crossing over because of this we're going to be highlighting as a final answer to our question. I really hope this video helped you and I hope to see you on the next one
