An important part of the design of variant calling methods using NGS data is the DNA sequence used as a reference to which the NGS reads are aligned. In human genetics studies, high quality references are available, from sources such as the HapMap project , [ 10 ] which can substantially improve the accuracy of the variant calls made by variant ...
Copy number variation (CNV) is a phenomenon in which sections of the genome are repeated and the number of repeats in the genome varies between individuals. [1] Copy number variation is a type of structural variation : specifically, it is a type of duplication or deletion event that affects a considerable number of base pairs. [ 2 ]
By using the ddRADseq method scientists found new sex-related loci in a 56 Gb genome of the family Cryptobranchidae. Their results support the hypothesis of female heterogamety of this species. These loci were confirmed through the bioinformatic analysis of presence/absence of that genetic locus in sex-determined individuals.
Copy-number variation (CNV) is a large category of structural variation, which includes insertions, deletions and duplications. In recent studies, copy-number variations are tested on people who do not have genetic diseases, using methods that are used for quantitative SNP genotyping.

Due to the CNV chromosomes of different sizes can be combined in a new cell. If this occurs around conception, the result will be a first cell of a human with a genetic variation. This can be either positive or negative. In positive cases this new human will be capable of a special skill that is assessed positively, for example, in sports or ...
