    I love Bio Questions!!, :laugh:
    Anyways:

    1. The equations to remember are p+q=1 and p^2+q^2=1

    well since you know the homozygous recessie (q^2) = .09
    then q=.3 and p =.7
    So, to figure out the heterozygous (2pq) = 2(.3)(.7) = .42 = 42%

    Please correct me if I am wrong, not good with genetics!!


    2. corals, anemones, hydra, jellyfish all belong to phylum cnidaria

    sponges = profira
    squids = molluska (cephalopods)
    starfish = echinoderms
    flatworms = phyhalmeniths

    Correct. The first question is of course one of many typos/busted questions in the Barrons book which is why 42% is not an answer.

    Yea, wait till you have like 10-12 days left before you take it! I have gone completely nuts! Dont worry, you will probably ace the practice tests and the real thing! As for me, gotta get back to studying!
