AI Thread Summary
Albinism in humans is determined by a recessive allele, represented as "rr." During meiosis, specifically at telophase I, an albino individual will have two copies of the recessive allele due to duplication during interphase. Each pole of the dividing cell will contain one copy of the allele, resulting in one "r" in each nucleus. Therefore, the correct answer to the homework question is D, indicating one copy of the allele at each pole. The discussion highlights the importance of understanding allele distribution during meiosis.

Homework Statement



Albinism in humans is controlled by a recessive allele. How many copies of this allele will be found at one of the poles of a cell at telophase I of meiosis in an albino person.
A.23
B.4
C.2
D.1

Homework Equations


The Attempt at a Solution


Let rr be the recessive allele for Albinism. During interphase, there will be 2 of rr due to duplication. Therefore, when they are sperated by the pole.
there would be 1 rr on the left and 1 rr on the right. Therefore telophase 1, will contain one rr in one nucleus and one rr in the other.

So my ans is D

Hmm i hav a 2nd attempt though and i think it shld be correct:
Let r be a recessive allele. A person with albino will be rr. Therefore, this wil duplicate during interphase resulting in 2(rr). Therefore, each pole will have 2(r). Therefore ans is C.
 
So, what's your question? ;-)
 
The question is on top liao. As for the attempt, it is the 2nd post

No, I understand what question you were asked. I see that you've answered it. Now, what is your question?

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
