I've been wondering how smart GAF really is so i found a few questions and i want to see how well GAF knows science.

1.How many sets of chromosomes are you born with. Where do the sets come from and how many do you get in each set?

2.A male = what two together?

3.A female = what two together?

Extra CREDIT

1.What is the phoenotypic ratio of SS (male dominant) x ss (female resesive) in its second generation?

EDIT: haha my bad S = Hairy s = smooth S+S = Large, Hairy s+s = smooth, silky. Sorry about that.

2.The gene for a sex-linked trait is associated with genes found on the X-chromosome.In man, hemophilia is due to a recessive gene; normal blood function results from a dominant one. This condition is sex-linked. If a normal woman whose father was a hemophiliac marries a normal man whose father was also a hemophiliac, what kind of probability ratios can be expected in their children with regard to hemophilia?

3.In man, the blood types A, B, AB, and O are determined by three alleles (multiple alleles). Any individual may possess only two of the three alleles. The alleles A and B are both dominant to O, but not each other (codominance).

A. What are the possible genotypes for each of the four blood types?

B.What kinds of children, with respect to blood types, might be possible from a marriage of a Type A person and a Type B person?

C.A child with bloody Type O is born out of wedlock to a woman with Type B blood. She names as the child's father a man with Type AB blood. How can the man Be innocent?



Good luck gaf.









*Note this is for my study on the average male and knowledge of science.

1.What is the phoenotypic ratio of SS (male dominant) x ss (female resesive) in its second generation?

Do you mean genotypic ratio? Wouldn't phenotypes require one to describe what dominant and recessive traits are represented (Ex: Blue eyes, brown hair etc.)?

 

[EviLore]

No one will want to take the chance on getting any questions wrong, so they'll google the answers and your results won't be accurate. You're better off issuing this in person.

 

[Drensch]

1. 46
2. xy
3. xx

The extracredit sounds like too much work.

 

[tetsuoxb]

Doing this off the top of my head and if I get them all wrong then fuck me.

1.How many sets of chromosomes are you born with. Where do the sets come from and how many do you get in each set?

23 sets. for a total of 46 chromosomes. 23 chromosomes from mother, 23 from father.

2.A male = what two together?

XY

3.A female = what two together?

XX

Ahh lets take a trip into the land of mendel.

1.What is the phoenotypic ratio of SS (male dominant) x ss (female resesive) in its second generation?

Generation 1:
      S  S
s    Ss  Ss
s    Ss  Ss

Generation 2:
      S    s
S   SS   Ss
s    Ss    ss

Ratio is 1:2:1 or 3 hairy, one being large hairy, and one being smooth silky.

2.The gene for a sex-linked trait is associated with genes found on the X-chromosome.In man, hemophilia is due to a recessive gene; normal blood function results from a dominant one. This condition is sex-linked. If a normal woman whose father was a hemophiliac marries a normal man whose father was also a hemophiliac, what kind of probability ratios can be expected in their children with regard to hemophilia?

Since a woman has 2 X chromosomes, it is possible that she carries the recessive gene which we will call h. Capital H is normal blood function.
H h
H HH Hh
h Hh hh

They should have a 1/4 chance of having a sick child.

3.In man, the blood types A, B, AB, and O are determined by three alleles (multiple alleles). Any individual may possess only two of the three alleles. The alleles A and B are both dominant to O, but not each other (codominance).

A. What are the possible genotypes for each of the four blood types?

B.What kinds of children, with respect to blood types, might be possible from a marriage of a Type A person and a Type B person?

C.A child with bloody Type O is born out of wedlock to a woman with Type B blood. She names as the child's father a man with Type AB blood. How can the man Be innocent?

A. Not sure on this one... but...
Type A - AA, AO
Type AB - AB
Type B - BB, BO
Type O - OO

B. Type A, B, and O

C. The mother's genotype is BO. The father is AB. They could only have a child with type A, B, or AB blood.



Next time.. just ask me to do your homework for you.

 

[B'z-chan]

tetsuoxb and drensch congrats to both of you.

And no this was not my homework. I'm already onto much more complicated crap. I really just wanted to see if GAF was smart enough to figure out this kind of stuff. Thanks for proving my theory.

You guys answered in less than 30 minutes. Which means something to my data.

If I got any of them wrong let me know... i never went to my college bio class because it was at 8 in the morning.. fuck that. so i taught myself.

 

[Cerebral Palsy]

I had this shit two semesters ago. I don't remember any of it.

 

[Iceman]

Being a biology PhD student I have exempted myself from this quiz.

I'll throw off the curve big time.

 

[happyfunball]

Im with Iceman




plus I FUCKING HATE genetics!!

 

[BigGreenMat]

I am with Iceman. This is seriously like 5th grade mendelian genetics though.

Another Biology PhD student here¡¡¡ What are you working on?

you tell that to my science teacher. She keeps saying were on track with the UC system. What BS. This is all pretty easy for me. Except for acids, thats the one thing i hate labs for. But genetics isnt really that hard. In fact i wouldnt mind becoming a gentesist. Kind of puts the fun out of natural selection in some ways.

Genetics is as much science as playing with dolls is.

Sorry, but could you please elaborate, 'cos I think you are dead wrong on that one.

 

[Son of Godzilla]

By playing with dolls we are able to recreate a modern domestic home environment and roleplay various scenarios in order to investigate the state of nature in said environment.

First, if you are going to roleplay, you don't need the dolls. Second, all that would lead to a complete disaster because you would be using people pretending to be somebody else, when you could easily simply study the Real Environment with Real Inhabitants .

But yes, Genetics is a Science.

Human Pathology at Univ. Wisconsin Madison. I work on glaucoma and the extracellular matrix, specifically the effect of fibronectin on trabecular meshwork cells. 3rd year student. Wow, those years (2.5) went by quick.

 

[yoshifumi]

1. 2 sets of 23
2. male = xy
3. female = xx

i'm too lazy to figure out the extra credit

edit: oh i see they've already been answered.

edit2: haha i thought that first extra credit was asking about a third generation and was trying to figure out all the ratios in my head.

But knowing genetics means you know science? GAF consists of average males?

 

[megateto]

It means you know a certain science, and if for you that doesn't qualify as "knowing science", I am not going to tell you are wrong.


I am working on brown trout population genetics, using microsatellites and sequencing of mitochondrial DNA.. not very exciting but hey, I am going to learn LOTS of statistics¡¡

 

[BigGreenMat]

megatato are you one of those hippie ecologists?

I am working on oligodendrocyte remyelination therapies in multiple sclerosis. Right now we are play with gamma-secretase inhibitors to short circuit the jagged/notch signalling pathway that 'seems' to stop myelination by oligodendrocytes in lesions in mouse models of demyelinating disease. I personally don't think notch inhibition will do a damn thing, but I am sure a couple papers could be made out of it.

 

[megateto]

Sorry for the bump, but I had a question to answer.

Hippie what???? I am surrounded by them, but I am not one of them.

It's very funny how things go at my Uni: if you have anything to do with Zoology, Botany or Ecology, chances for having an ecologycal hippie are HIGH, and if you look into anything biotech related stuff, you have the pro-everything people. More or less.,

Seems we should make the Biologists Gamers Union at GAF, or somehing. I feel so lonely over here (I don't like PES and that's the only thing my fellows seems to enjoy playing).
