Methods for generating databases and databases for identifying polymorphic genetic markers

摘要

A method for discovery of a polymorphism in a population is provided. The method includes the steps of obtaining samples of body tissue or fluid from a plurality of organisms; isolating a biopolymer from each sample; pooling each isolated biopolymer; optionally amplifying the amount of biopolymer; cleaving the pooled biopolymers to produce fragments thereof; obtaining a mass spectrum of the resulting fragments; and comparing the frequency of each fragment to identify fragments present in amounts lower than the average frequency, thereby identifying any polymorphisms.
