Re: CCEA Biology A2:2yeo lopikase haha yeah few questions v dodgy. second part of essay was vague though, a number of things could have been said(Original post by lopikase123)
haha there were some nasty bits, and like that nitrogen cycle stuff??? eh wrong paper?? the essay was ok though i thought what about you guys? -
Re: CCEA Biology A2:2why what wasnt on the spec?? there was no 'peer review' type stuff like that which came up on paper one. The whole plasmi/vector thing was stariaght from the book it was nice, they even used the exact diagram in the transcription questiion lol(Original post by jamster1991)
the only saving grace of that paper was the essay. Are they allowed to put things that blatantly arent on the spec onto the paper? There are gonna have to scale that up something shocking if everyone found it as hard i did. -

Re: CCEA Biology A2:2i just went for more common in males than females(Original post by lopikase123)
can i ask how you proved that it was sex linked?? is it simply that all affected were male ? its just that that doesnt really seemed like proof more than just a high liklihood -
Re: CCEA Biology A2:2yeah i couldnt prove it exactly, I just said that all males had it, and since they only need to have the non functional gene once (one X chromosome) then they are more likely. I dont know how you can prove it exactly(Original post by lopikase123)
