Oh, and what did you put for what the person with the pond should also look at about the plant? In the end I wrote, "What it looks like" :wink: hehe


I put the conditions it lives in?
I think the answers might have been, how large it grows? :confused:

You could be right, I'm not claiming I am (I found it pretty hard :frown:)
But I imagine they'll probably allow 7-8 or something?
What was the absolutely last question?
I put it was a carrier?:confused: No idea.

thats correct! well done! u had to say 75% have the disease. 25% are normal.


I wrote down the ratio of having disease to not having disease was 3:1. Is this right, will it matter if i didnt get the allelles correct. I put Hh and hh i think.

I put something about how things don't always conform to probability and that there was a chance that it was Hh because if all of the offspring had gained the H then they would all have it... :smile: but it could aslo have been HH cos none of them didn't have it.

what did everyone put for the capsule one? said it needs to be in a capsule because if it was released it would go in the stomach which had a high PH. this wuld denature the enzyme. what did everyone else get?

I wrote something about how if it needs to get to a certain place to be used, then it needs to dissolve in that place, and that place only, hence why the lipase would be the enzyme to digest the outer coating.
