The use of the X chromosome in population genetics is still in its infancy.It has already proved its worth in studies of the early history of modern Homo sapiens,but in most research areas its potential remains largely untapped.That potential is needed — the Y chromosome and mtDNA,despite their enormously fruitful contributions,are not very informative about some questions (such as the size of ancestral populations),and the information that they can provide about others (such as population history before the Out of Africa migration) has largely already been mined.The X chromosome is therefore the logical place to turn for more information.Many of the same questions can be addressed by either the X chromo-some or the autosomes,but the X chromosome has a clear advantage in allowing easy access to haplotypes; the cost of extracting haplotypes from autosomes remains high,even as sequencing and genotyping become much faster and cheaper.

对X染色体的使用在群靉体遗传学中仍处于初级阶段.这一应用已经在研究现代人类的早期历靉史中发挥了作用,但在其他领域仍有着巨大潜力.这一潜力需要挖掘——Y染色体和mtDNA,尽管有着多种巨大的贡献,但对于某些问题无法提靉供充足的信息（例如原始人族群规模）,而它们在其它问题（例如非洲大迁徙之前的族群历靉史）中能提靉供的信息已经被充分发掘了.因此X染色体也就合乎逻辑的成为了更多信息的来源.很多问题能同时被X染色体或常染色体解决,但X染色体有着如下优点：容易获得单体型；从单体型中提取常染色体的成本仍然很高；甚至排序和基因构建也更快更便宜.
