Answer 1

Should i reply ?

Answer 2

I dont care .

Answer 3

Why not

Answer 4

Since the asker has tagged u @flvsguy !

Answer 5

don't want to interrupt

Answer 6

Someone help me !

Answer 7

Well recombination frequency is the result that two chromosomes that are not parental cross over, for example if the parent AB and ab cross, and they get a inheritance of Ab, this is not a parental type and is a recombination. Got it so far?.

Answer 8

Well, its not A

Answer 9

Yeahh , i got it so far .

Answer 10

I would say B but you'll probably want to hear someone else out on this one also to make sure. so wait for alpha's reply

Answer 11

Great, well from what I said, you should by now learn that in class your teacher will talk about the distance the two genes are away from each other (Like I said example AB and ab cross to produce Ab) That means there has been a crossing over in prophase of meiosis I.

Answer 12

Yes its B, frequencies can be used as a measure of distance between two genes. This in turn can be used to build a chromosome map.

Answer 13

The whole point of recombination frequencys is to figure out if 2 genes (AB, ab, Ab, aB) are going to be linked together (AKA are going to be inherited together, if they are inherited together that means they are very close to each other on the chromosome, and they are not always inherited that means that they are far apart from each other.

Answer is B.
