Disclosed herein are methods to determine the abundance of nucleotide sequences relative to other nucleotide sequences in a complex genome.

Oligonucleotide primers and probes for quantifying and/or detecting human male DNA in a forensic sample. The oligonucleotides are useful for amplifying a multicopy locus within the human Y-chromosome (MCL-Y) that shares at least 80% sequence identity to a sequence according to SEQ ID NO. 3 over a stretch of at least 60 base pairs. The oligonucleotides hybridize under stringent conditions to a nucleic acid having at least one sequence selected from the group consisting of SEQ ID NO. 3 to SEQ ID NO. 11 and/or SEQ ID NO. 17 to SEQ ID NO. 25. Kits including the oligonucleotide primers, probes and/or primer pairs and reagents for performing an amplification reaction on DNA recovered from a forensic sample are also disclosed.

The present invention relates to a method capable of, in order to diagnose fetal sex chromosome aneuploidy, differentiating Kleinfeiter's syndrome (XXY), triple X syndrome (XXX), and Turner's syndrome (monosomy X, XO) as well as male (XY) and female (XX) by using copy number variation (CNV). The differentiation method according to the present invention has significantly high sensitivity and accuracy since the reference line is evenly adjusted by performing normalization regardless of the kinds of platform and data. The present invention is useful in diagnosing the sex chromosome abnormality at an early stage through easy diagnosis of sex chromosomes X and Y, which are hard to diagnose, since an analysis is possible even with a small amount of fetal chromosomes, which corresponds to an advantage of noninvasive prenatal diagnosis, and copies are redundant.

The disclosure provides methods and compositions, e.g., kits, for identifying or authenticating a sample, e.g., a tumor model, based on the genotype of the sample at a group of SNP loci.

The present invention discloses a PIS genotype detection method for goats and belongs to field of life science. The method includes 4 pairs of specific primers: SRY F and SRY R; PIS wt F and PIS wt R; PIS var-1 F and PIS var-1 R; and PIS var-2 F and PIS var-2 R, and a probe. The present invention further provides a specific detection method and a detection standard. A simple and efficient detection method for diagnosing a PIS genotype of the goats is developed in combination with a high-sensitivity PCR method and a high-stability Southern Blot method, has extremely high specificity, is convenient and rapid, and may be used for accurately identifying genotypes of PIS genes, guiding breeding and mating of the goats and controlling or adjusting genotype frequencies of the PIS genes in goat populations according to requirements of breeders, to increase economic benefits of goat farming.
