Hi can some explain the Hardy-weinberg principle to me. I was reading over my older bio book-it's been a while since I took bio)
here is the example:

population of 100 cats; 84 are black 16 are white

what are the values for each allele and how did you get the value?

Thanks

Dinene RDH, BA 🙂

Hope this makes sense, and I could be wrong 🙂

#define
Black = BB, Bb
White= bb
q^2+2pq+p^2=1
p+q=1
-----------------

P2^2=white (homo res)
so...
root(16/100) = .4 = p allete
1-.4=.6 = q allele

To for a step farther, as some questions might ask:

q^2 = .36 <--- Homozygo Dom Freq
2pq = .48 <---Hertozyg Freq
q^2 = .16 <---Homozyg Res freq
___________
= 1 so that checks
