You obtain 6 BACs (of known order, as shown below) and 7 STSs (of unknown order) that derive from a region of mouse chromosome 16 whose genomic sequence has not yet been finished.   

 

By PCR (using 20-bp primers at either end of each STS), you test each of the 6 BACs for the presence (+) or absence (-) of each of the 7 STSs. You obtain the following results:

 

How would you use the sequence information presented in to design two new STSs (with new PCR primer pairs) to replace STS5? (Call the new ones STS51 and STS52. STS51 should be present (+) in BAC B, and STS52 should be present (+) in BAC F.)

if the forward ( p in to q) and reverse ( q in to p) mutation rates for alleles at a locus are 1×10−1 and 1×10−2 per generation, respectively and the allelic frequencies are p = 0.20 and q = 0.80. if you assuming random matting population. Which of the following observation correct?
