Abstract: This disclosure provides methods and systems useful in array-based analysis of mixed nucleic acid populations, including for multiplex genotyping of a mixed nucleic acid sample and for detecting differences in copy number of a target polynucleotide and/or a target chromosome (e.g., microdeletions, duplications and aneuploidies). The disclosure also provides methods and systems useful in the diagnosis of genetic abnormalities in a mixed nucleic acid population taken non-invasively from an organism, such as a sample of blood, plasma, serum, urine stool or saliva. The disclosed methods and systems find use in multiple applications, including prenatal testing and cancer diagnostics.

The disclosure is based on the hybridisation of amplified fragments from the sample, e.g. a maternal sample, which may employ molecular inversion probes MIP to an oligonucleotide array and the detection of the alleles based on different signals from the different alleles of the SNP.

Abstract: The present invention generally provides a rapid efficient method for analyzing polymorphic or biallelic markers, and arrays for carrying out these analyses. In general, the methods of the present invention employ arrays of oligonucleotide probes that are complementary to target nucleic acids which correspond to the marker sequences of an individual. The probes are typically arranged in detection blocks, each block being capable of discriminating the three genotypes for a given marker, i.e., the heterozygote or either of the two homozygotes.

Abstract: The present invention relates to novel methods for sequencing and mapping genetic markers in polynucleotide sequences using Type-IIs restriction endonucleases. The methods herein described result in the “capturing” and determination of specific oligonucleotide sequences located adjacent to Type-IIs restriction sites. The resulting sequences are useful as effective markers for use in genetic napping, screening and manipulation.

Abstract: The invention provides oligonucleotides and their complements that can be used as allele-specific probes or primers for sequencing, oligonucleotide probe hybridization, and allele-specific amplification. Such oligonucleotides can be used, for example, to facilitate genetic distinction between individual plants in plant populations.
