Question
*** My eexperiment was to track free and attached earlobes in 1) 50 people and then experiment 2) in women and men, My results were as follows.
47 people had free earlobes and 3 people had attached earlobes.
and then:
Men had 24/25 had free earlobes
Women had 23/25 had free earlobes.
Please help me with the questions below. *****
Now you need to calculate the Hardy Weinberg p and q values for the BASELINE and EXPERIMENTAL datasets. The Hardy Weinberg equation is p2+2pq+q2=1.
The Hardy Weinberg equation has a rule where the dominant allele is always called p and the recessive allele is always called q. Do you remember which trait is dominant in this study?
p= ______________ earlobe allele
q=______________ earlobe allele
Since you do not know which people are heterozygous (have one dominant and one recessive allele) you will have to determine your HW values from people who are homozygous recessive (because you can SEE that they have the recessive trait from two copies of the recessive allele). The percent (as a decimal) of the homozygous recessive people out of the total number of people is q2.
Now for the numbers:
q2= number of homozygous recessive people in group divided by the total number of people in group
q= the square root of q2
p = since p+q = 1; p = 1-q
After you calculate your values for the baseline and each of the experimental groups, enter the information in the data table below.
