Sexual dimorphism (SD) is a pattern that is seen throughout the animal kingdom and differences between the sexes in coloration are common in many organisms. Following some statement are given

A) There are many mechanisms that drive the evolution of SD, the most accepted mechanism being sexual selection

B) Mate choice is an important proximate mechanism of sexual selection, often the sex with the higher reproductive investment is the ‘choosy’ sex

C) Larger species are more sexually dimorphic than smaller species

D) Terrestrial species tend to be more sexually dimorphic than arboreal species

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.)
