<p>It was in M
it’s 100% and 50% (2 separate questions), if i remember correctly.</p>
<p>yay, okay thanks. i’m still not sure why the second question is 50% though…</p>
<p>umm (if i remember correctly), the mother (daughter of the first generation) was dominant (given) and she had to be heterozygous since HER mother was heterozygous and her father was recessive. The mother (daughter of the first generation) marries a recessive man, so thats also a Ff x ff cross which results in Ff, Ff, ff, ff, so 50% right?</p>
<p>oh i guess i did see wrongly then, i thought the first generation were both heterozygous. ;( how on earth did i see an unshaded square as a shaded square T_T</p>
<p>OK, here’s how it went. The FIRST generation both had to be heterozygous DOMINANT (because they had a recessive kid, and one dominant daughter.) I clearly remembered they were both shaded. </p>
<p>The DOMINANT daughter married a recessive man, and gave birth to ONE recessive male and ONE question mark. The Parents 100% were both heterozygous dominant. The daughter who was dominant who married the recessive man HAD to be heterozygous, because she carried the dominant trait but had a kid who was recessive. If she was HOMOZYGOUS, that wouldn’t have been possible. So the phenotype of the ? was 1/2, due to the Dd x dd cross.</p>
<p>Hmm btw… did you guys get two genetic drifts for the matching section:</p>
<p>They were like:
Population expresses a different set of traits after a disaster </p>
<p>and </p>
<p>Random loss of traits over time in a small population</p>
<p>@mowmow721 okay i totally didn’t see the recessive kid then. ): -1.25, bah.</p>
<p>@rtgrove123 nope, i put natural selection for the first and genetic drift for the second.</p>
<p>the matching was natural selection, mutation and genetic drift</p>
<p>U sure about tht…if a population that survives has a different gene pool than that beforer…thats bottlenose effect which is a form of genetic drift</p>
<p>i think you have the question wording mixed up.
it was definitely natural selection, mutation and genetic drift,not necesarrily in that order though</p>
<p>Do you remember the question word…dang I am ****ed…I am at -4 (I HATE THAT STUPID -1/4 a point thing!!!)</p>
<p>umm im not sure what it was for natural selection
but the mutation was like new traits in an isolated population
genetic drift was loss of genetic variation due to chance or something like that</p>
<p>K…ya I got the mutation and last genetic drift problem…dang tho cant believe i missed that first one!</p>
<p>Anyone know when they release these scores?!?</p>
<p>I think they’re released on October 29th.</p>
<p>and…the sensory vs motor nerve question, is the answer confirmed to be motor? x.x</p>
<p>yeah…</p>
<p>I think I got all the xylem, phoelem, guard cell thing wrong. lol</p>
<p>I also got true breeding wrong.</p>
<p>Can anyone tell me why the one w/crab populations wasn’t burrow density? 
My friends put density as well, so.
^Was true breeding that the offspring exhibited same phenotype?</p>
<p>i said substrate. wasn’t it substrate? one group liked the mud, the other the sand? that didn’t seem like a difficult one at the time, but what do i know…</p>
<p>edit:</p>
<p>yeah, it was that.</p>
