    hey guys
    i was just doing some past papers when i came across this question in some paper:
    Some animals are known as endangered species because there is only a small number
    of individuals left in the wild. Zoos may try to increase the number of these animals by
    breeding them in captivity. For greater success, a breeding pair should be unrelated.
    Explain how genetic fingerprints can be useful in selecting animals for breeding.

    I dont understand wht this question want. could some1 be kind enough to explain this 2 me
    thanks

    1. explain what a genetic fingerprint is, how it would be done (gel electrophoresis), what it shows
    2. say how, by comparing fingerprints from different animals, you could figure out how closely related they are (i.e. the more similarity the closer the relationship)
    3. you could use this info to breed animals who have a diverse range of alleles stopping inbreeding depression (maybe a bit about what this is... how many marks for the Q?)

    Yeah, I've done this question before. All you have to say is something like you can use a genetic fingerprint to make sure the two animals aren't related so aren't bred with each other.

    ...or you could just check the markscheme on the AQA website :p:
