98 geographically separated populations in the same species, and markers for following the movement of African bees in the USA. The sequences obtained for the pG178 subclones will be used to design primers which can be used to convert the RFLP analysis to a more expedient PCR format. It is predicted that by amplifying each region in the samples containing the different Mspl and Ddel variants, the site and length polymophisms which define each variant can be identified.
