<p>Generally when they’re asking for percent chances of certain crosses they GIVE you the genotype of the parents. Like for the set with tall/dwarf and red/white/pink flowers. Each parent’s genotype was given for the crosses. So if they didn’t give it, I think assuming that the genotype is one without any evidence might not be the best choice.</p>
<p>I think this was my best test! :)</p>
<p>i don’t even think averaging those probabilities would be correct
if they’re independent, which they would be, you would have to multiply them right?
and you’d still get .5</p>
<p>i’m actualyl sure HH isn’t even possible…the kid would already be dead lol</p>
<p>I thought it would decrease since PTH increases blood calcium</p>
<p>yeah HH = bad news bears</p>
<p>Are we still talking Hungtington’s here? Clearly it was 50%. Why are we even arguing about it?</p>
<p>Or with HH, the dad would die before he could have a son…</p>
<p>On E, there were 3 trophic levels in the terrarium…,or what did you all put? (clovers and grass = 1, termites and something else = 2, salamander = 3)</p>
<p>Yeah nns I thought that at first, but then I considered that PTH serves to regulate blood calcium levels through negative feedback right? So I figured that if the parathyroids were removed calcium levels wouldn’t be regulated and maintained in the correct range, so they would fluctuate greatly (too much/too little) depending on how much calcium was being taken in by the person.</p>
<p>On M- I thought the weird questions were with the labeled O. Can we discuss that? Anyone who knows what I’m talking about?</p>
<p>If you remove the Parathyroid gland, the amount of hormone is going to decrease.</p>
<p>Was that one of the options? I don’t remember what I put, but something decreasing.</p>
<p>We’re talking about the question that asked what would happen to calcium levels if the parathyroids were removed, not the one that asked what would happen to levels of PTH.</p>
<p>Oh oops. My bad. </p>
<p>I think I said increase?</p>
<p>I said that the body would do something to increase the levels.</p>
<p>For PTH there was:</p>
<p>1 Parathyroid is removed, what happens to PTH? - decreases
2 Parathyroid is removed, what happens to calcium? - I put decreases b/c its not a response to calcium, the parathyroids are just removed for no reason. Since there’s no PTH anymore, Ca levels will decrease. It could also fluctuate b/c of eating as someone said earlier. Clarify?</p>
<p>Question: Was Tay-Sachs disease lysosome? and bacterial resistance one: was it ampicillin caused mutation or were there already resistant bacteria?</p>
<p>About the Huntingtons…I think Josmur is right. I put 50% but I definitely see his logic. And I dont think that the father would die as a child if he was HH becuase huntingtons disease usually manifests in late age. so according to that, its possible that he could be homozygous as well as heterozygous =/. It makes sense</p>
<p>Yeah did anyone else feel that the graph felt “reversed?”</p>
<p>Yeah I did, but then I understood because the hormones and stuff will work towards maintaining 100:100</p>
<p>What was the answer to the Mendel question?</p>
<p>Quantitative experiments</p>
