sorry if this has been said but there are a few things i find wrong with roswell that ends well

first why does enus have hair exatcly the same as fry 

second  fry call enus's nuts dad but his mum is the one with the red hair

grrrr... now explain

Brown hair is a dominant gene.  Red hair is a recessive gene.  Somebody feel like drawing up a Punnit square to demonstrate the probabilities of Fry's hair color?

Oo oo me me!

Now, assuming Enos Fry was, in fact, Fry's grandfather (he wasn't, as it turns out), he would have two Red-Hair Alleles, which are recessive alleles of hair color.  Mildred had either two Brown Hair Alleles or a Brown Hair Allele and a Red Hair Allele - here hair would still be brown either way, as a Brown Allele dominates a Red Allele.

The offspring of any pairing gets one allele from each parent, thus there are four possible combinations for a given set of parent alleles, as shown below:

r = red allele (mutated blonde allele, if you're curious)
B = brown allele

Code: [Select]

   r    r
 -----------
B| Br | Br |
 -----------
B| Br | Br |
 -----------

   r    r
 -----------
B| Br | Br |
 -----------
r| rr | rr |
 -----------
Thus, if Mildred had two brown alleles, any offspring would have a brown allele and a red allele, and thus have brown hair.  If she had a brown allele and a red allele to begin with, there would be a fifty-fifty chance of her offspring with Enos having brown (Br) or red (rr) hair.  In the case of Yancy Fry, his hair was brown and thus he has a brown allele and a red allele

Now, from the above, we know that Phillip J. Fry I's father has a B and an r allele, and that his mother, who has red hair, has two r alleles.  Thus, Fry's parents would create a set of possible offspring exactly like the second square above, meaning there is a fifty percent chance that any given child of theirs is a redhead, and a fifty percent chance that any given child has brown hair.

They had two sons: one with red hair, one with brown.  QED.

The most brilliant part of all of this is that it still works when you consider that Phillip J. Fry I is in fact his father's father, not Enos, as they have the same set of hair alleles.  It gets a little more complicated and unlikely when you consider his entire genome, however, and I won't get into that.

thanks i'm beginning to get it
coincidentlly i started reading a "principals of genetics"

thanks guys

Is brown a mutated gene from black or vice-versa? This may be a very stupid thing to ask, but I don't have a degree in bio-science or whatever...

[Reply #5 on:]

Actually yes, I believe so seeing they're both dominant.  Not sure however, I'm a CompSci major.

sorry to get off-topic,
but why is fry's mom a cheeze-head if they live in new york?

odd place for a packers fan.

btw: Go Bears.

Because, you know, people never move.

Also, the original questions were answered, so away we go into the PEEL museum, after cleaning up after the morons.
