Chromosome 6 spans nearly 171 million base pairs (the building material of DNA) and represents between 5.5 and 6% of the total DNA in cells. It contains the major histocompatibility complex , which contains over 100 genes related to the immune response , and plays a vital role in organ transplantation .
Genetic variation Genetic variation of Eurasian populations showing different frequency of West- and East-Eurasian components [56] It is commonly assumed that early humans left Africa, and thus must have passed through a population bottleneck before their African-Eurasian divergence around 100,000 years ago (ca. 3,000 generations).
Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either quantitative traits (traits that vary continuously and are coded for by many genes, e.g., leg length in dogs) or discrete traits (traits that fall into discrete categories and are coded for by one or a few genes, e.g., white, pink, or red petal color ...

Genomic structural variation is the variation in structure of an organism's chromosome, such as deletions, duplications, copy-number variants, insertions, inversions and translocations. Originally, a structure variation affects a sequence length about 1kb to 3Mb, which is larger than SNPs and smaller than chromosome abnormality (though the ...
Scientists have taken an important step forward in understanding the human genome - our genetic blueprint - by fully deciphering the enigmatic Y chromosome present in males, an achievement that ...
(1,2) When two chromosomes misalign, crossing over - the exchange of gene alleles - results in one chromosome expanding or increasing in gene number and the other contracting or decreasing in gene number. The expansion of a gene cluster is the duplication of genes that leads to larger gene families. [6] [8]
