Task: Question Generation
Input (English): The archeological record indicates that the permanent settlement of Cyprus began with pioneering agriculturalists circa 11,000\xa0years before present, (ca. 11,000 y BP). Subsequent colonization events followed, some recognized\xa0regionally. Here, we assess the Y-chromosome structure of Cyprus in context to regional populations and correlate it to phases of prehistoric colonization.', 'Analysis of haplotypes from 574 samples showed that island-wide substructure was barely significant in a spatial analysis of molecular variance (SAMOVA). However, analyses of molecular variance (AMOVA) of haplogroups using 92 binary markers genotyped in 629 Cypriots revealed that the proportion of variance among the districts was irregularly distributed. Principal component analysis (PCA) revealed potential genetic associations of Greek-Cypriots with neighbor populations. Contrasting haplogroups in the PCA were used as surrogates of parental populations. Admixture analyses suggested that the majority of G2a-P15 and R1b-M269 components were contributed by Anatolia and Levant sources, respectively, while Greece Balkans supplied the majority of E-V13 and J2a-M67. Haplotype-based expansion times were at historical levels suggestive of recent demography.
Output (English): Does y-chromosome phylogeographic analysis of the Greek-Cypriot population reveal elements consistent with Neolithic and Bronze Age settlements?
