Hardy weinberg's princple - (Sep/01/2008 )

can some one please tell what does the folowing lettersb
p
q p²

q²

and 2pq
stand for?

---

p,q allele frequencies for example if there are only 2 possible alleles (p and q) and they are equally common that would be 0.5 (=50%) for both

p² chance that p is present in both chromosome sets
q² chance that q is present in both chromosome sets
both would be 0.25 in our example (=0.5x0.5=25%)

2pq change that this trait is heterozygous so one chromosome set has p and the other one has q
why is it times 2? because it can either be pq or qp which is irrelevant (in most cases)
so for our example it would be 0.5 (2x0.5x0.5=50%)

hey im sorry my question was a little bit mistyped
i want to know what do these elements stand for in the Hardy- Hardy Weinberg's equilibrium?
p
q
p²
q²
2pq
no examples needed, i know how to do the problem n thx for helping but I want the definitions,
its a question in my exam paper.
ok now? i hope my querry is clearer now?
n thx again for the explanation

---

but thats what I did explain

---

Also, try asking in the homework forum (for all the questions you posted today) as these questions are clearly homework!!!

---

its not homework but questions that came in exam,
n Coastal, our teaher is telling something quite different, that doesnt go in my head so im sorry if I offended you.
