Question

Does anyone know how to solve this question? I've been trying butcan't seem to get it right. If anyone could help me I would greatlyappreciate it.
Suppose there are 5000 people in an Amish community, whichmeets many of the assumption of the Hardy-Weinberg Principle. Agroup conducting a census counting number of people with each haircolor in the community above for a genetic study has completedcounting the blondes (1375 total), and has asked you to makepredictions about their count based on the preliminary dataprovided to you.

a. What is the genotypic ratio of blondes (bb) in thepopulation?


b. Using the Hardy-Weinberg principle, predict thefollowing.


c. What is the frequency of the homozygous dominant (BB) genotype,and approximately
how many individuals within this population have it?


d. What is the frequency of the recessive b allele in the entirepopulation?


e. If we find that marriages, and therefor matings, within theAmish population we are
analyzing are arranged by the parents, one of the assumptions ofthe Hardy-Weinberg
Principle has been violated. Which assumption?


f. Upon interviewing the sampled Amish families, the census teamfinds that 4 families moved into the village you are studying froma town in northern Indiana. Which assumption has beenviolated?

Explanation / Answer

Suppose there are 5000 people in an Amish community, which meetsmany of the assumption of the Hardy-Weinberg Principle. A groupconducting a census counting number of people with each hair colorin the community above for a genetic study has completed countingthe blondes (1375 total), and has asked you to make predictionsabout their count based on the preliminary data provided toyou. total population= 5000 people blondes = bb= 1375 BB    Bb      bb p2 2pq         q2 q2=blondes = bb= 1375 /5000 q=.52 p+q= 1-.52= .48 BB    Bb      bb p2 2pq         q2 BB=p2 = .48 x .48=.2304-------NORMAL--------HOMOZYGOUS Bb=2pq =2 X..48 x .52=0.4992-----NORMAL-HETEROZYGOUS bb= q2=.52 X .52=0.2704----------blondes ----HOMOZYGOUS
