   Process of elimination says B…blastoderm fate mapping.

   A. is a method for quickly making many DNA copies
   B. is a study of the cells in an early embryo stage
   C. is the locating of genes on the chromosomes (product is the genome)
   D. is a technique for studying an individual’s genes for abnormalities
   E. is a method for locating genes on chromosomes (produces the light & dark bands that distinguish one gene from the next)
