1. A method for genotyping of one or more polymorphisms, comprising:
- pooling a first library of amplified DNA fragments and a second library of amplified DNA fragments to obtain a pooled DNA library, the amplified DNA fragments of the first library comprising DNA sequences amplified from a first sample by solution PCR and a first unique identifier sequence, the amplified DNA fragments of the second library comprising DNA sequences amplified from a second sample by solution PCR and a second unique identifier sequence, wherein the first and second unique identifier sequences indicate different sample origins of the first and second libraries;
sequencing the pooled DNA library using high throughput sequencing technology, comprising amplifying on a solid support;
clustering sequences of the first and second libraries of amplified DNA fragments; and
determining dominant or co-dominant genotype(s) of one or more polymorphisms in the first and second libraries of amplified DNA fragments using the first and second unique identifier sequences.

Abstract
The invention relates to a method for the high throughput discovery, detection and genotyping of one or more genetic markers in one or more samples, comprising the steps of restriction endonuclease digest of DNA, adaptor-ligation, optional pre-amplification, selective amplification, pooling of the amplified products, sequencing the libraries with sufficient redundancy, clustering followed by identification of the genetic markers within the library and/or between libraries and determination of (co-)dominant genotypes of the genetic markers.
