Course:BIOL121/bluepeople45

Hi everyone. So I think we should all upload our answers as soon as we are done the assignment. Just log in and click the edit tab at the top to add stuff to the page. Make sure you click the signature button after you write down your work so we know who wrote what and it isn't confusing. Also space out the work so there's at least a couple lines of space in between entries. I will upload my answers later tonight. --StellaTung 02:14, 8 March 2010 (UTC)

Here is what I've come up with for the assignment. Not sure if my answers are correct, so feel free to add/change or just put your own onto the page.

1. Consistent: - no mutation - no gene flow – isolated clan that often mated within family - no genetic drift – no random addition or loss of allele Inconsistent: - non-random mating, though mated within family - natural selection: not all parents contributed same # of gametes to the pool

2. a) frequency of mm = 0.23

b) frequency of MM = 0.27

c) frequency of Mm = 0.50

d) frequency of m allele is 0.52; comared to other populations listed it is much higher in frequency

e) Large discrepancy between Fugate clan and Basque population could be explained by intermarriage of the Fugate clan, because the mating of carriers of the mutant allele causes it to become more widespread through generations.

3. Gene flow is occurring as individuals of newer generations in the population leave to other populations and breed. This will cause the m allele to become less frequent within the gene pool of the community, which is further pronounced by new populations being introduced into this area.

4. If birth weight occurs as a stabilizing selection, and if larger birth weight is favoured, then genotype mm is also favoured by coincidence. The consequences of this coincidence would cause the m allele to be more frequent in the gene pool.

Hey everyone, so this is what i got so far, I agree with all of your answers stella! Im having a hard time figuring out number 2 allele frequencies, so not sure if it is right at all...

1. Conditions which are consistent with the hardy wheingberg principle are:

- allele frequencies are not changing over time
- no mutations
- there is no gene flow occuring as well as genetic drift.
Conditions which are inconsistent would be:
- there is non random mating occuring, with individuals from the same gene pool interbreeding with one another, causing no gene flow to occur, and mutations to arise.

2. Ummm yeah so this one is not very good for my numbers i got a) mm = 0.23 b) (MM) = 0.36 c) (Mm) = 0.40 d) dont know e)the large discrepancy could be explained between the basque and fugate clan by their interbreeding with one another, causing the mutation of the NADH diaphorase to become more of a widespread mutation amongst the members of the fugate clan. There will be more carriers of this mutation as well.

3. There will be gene flow occuring, with new gene pools mixing and breeding with the fugate generations, causing the m allele frequency to become less frequent.

4. The form of selection that acts on birth weight is stablizing selection, which will also favor the mm allele frequency if larger birth weight is favored. The consequences would be, is that the m allele will become more frequent in the gene pool of the fugate clan. --LeilaPolzer 18:38, 8 March 2010 (UTC)Leila

Berlin: I just want you to know, my answer is posted on the discusstion section yesterday.

Leila: Yeah i saw that, so what do you guys think we should do,our other member hasnt written anything yet.

There are two ways, we do them a favour just added there names and student number in, or told the teacher. I think I will go the first one.
