    So first of all, reproductive isolation is just the general term for when 2 populations of the same species cannot breed. Geographical isolation is a type of reproductive isolation, and is when a population of a species is separated into 2 populations by a physical geographical barrier, such as mountains or water. This prevents the populations from breeding. In the 2 new habitals formed, different environmemts lead to SELECTION PRESSURES, which in turn select for the most desirable phenotypes and genotypes. Over many years of this, the gene pools of the 2 populations become very different, and if the 2 populations were to be integrated again, they would not be able to produe viable offspring. This is speciation. I think that's all right, it's been a while since I've done this haha
    Thank you!! And at least you remember it haha - I wouldn't tbh

    Yh sure, I'm not sure what the rules are surrounding this, but I'm sure predicting what might come is fine. And I have my unit 5 notes, I guess I can try and post them on here, let me try

    Right I've tried sharing my notes, but nothing works, if people are really desperate for them, then I could share them in a more private way such as email or facebook, but I know that will probably seem really dodgy as we're all just people sat behind computer screens! Up to you guys, let me know

    Flash cards, with the ion on the front and the answer on the back. Look for patterns too, you'll find that a lot of them are similar (all Al ions are colourless for example). Just in general, write them all out a colour code them, learn as many as you can and then do flash cards until you know them all. It takes a while, I kept getting the odd one wrong, just learn which one you got wrong and do the flashcards again until you get them all right. If I remember, over easter when I'm back at home I'll send a picture of my colour coded notes

    Oops sorry I missed equations. Don't do flashcard for these, just write them out and learn them. Again, look for patterns, I had some good ones which I can't quite remember (again, if I remember I'll send them). Things like "metals that begin with C react with excess ammonia" or something

    Hey, I am stuck on a few bits in the 'applying rDNA technology' section of AQA A2 Biology. I don't really understand the following parts:

    Gene Cloning and Transfer (in vivo/in vitro etc)
    DNA Probes and Restriction Mapping
    Genetic Fingerprinting

    I would greatly appreciate it if you could explain them to me. Thank you!

    Okay, these are really big areas to try and explain, especially in one message (and although I may be a nerd I'd rather not spend ages explaining all of these things :P), so there are 2 things I can do, I could answer any specific problems you're having in these areas, and also, if you want, I could send you my AQA A2 unit 5 notes which explain recombinant DNA tech pretty well I think.

    Would you suggest writing your own notes or just learning some pre written ones and doing past papers

    No problem, I think sending your notes would be a better idea because I'm stuck on the topic in general rather than little parts. So if you could send me your notes I will greatly appreciate it
