4. Compute F-statistics and infer genetic differentiation.        
Flower color of desert snow (Linanthus parryae) is controlled by one locus with two alleles (P and W, for
pink and white, respectively). A river divides the area into two regions. Three subpopulations (Demes) were
sampled from each region, with genotype frequencies shown by Region and Deme in the table below.

sampled from each region, with genotype frequencies shown by Region and Deme in the table below.
Compute F_IS, F_SR, F_RT and F_IT, and answer the questions based on your results.
E(P_PW) expected PW genotype frequency, p_Deme: allele frequency of the P allele in a deme. _S' and '_R'
indicates subscripted subpopulation and region, respectively.

Is there much inbreeding within each deme (Yes/No)?
Answer:
Most of genetic differentiation is observed
1. between demes within each region.
2. between the two regions.
Choose either 1 or 2:
