Sentences with phrase «y haplotype»

Given what we expect to be strong purifying selection acting to reduce diversity on the Y, the same arguments, of ancient population structure or even archaic introgression may still apply to this unique Y haplotype.

While the new Y haplotype does increase the diversity, and thus the TMRCA, the TMRCA calculation is extremely sensitive to the mutation rate used.

By linking the Y chromosome lineages with genealogical information derived from written records, the researchers say it's now possible to define Y haplotypes for certain founder stallions.

Not exact matches

«Many Y - chromosome haplotypes co-existed within Scythian horse populations.

During the same time period, reproductive management has involved an increasingly reduced number of stallions, up to the point that, today, almost all domesticates virtually carry the same, or highly similar, Y - chromosome haplotype (s).

Y - chromosome haplotypes were recovered by aligning reads against previously identified Y - chromosome contigs (12, 75), first against the contigs alone and then remapped against the full nuclear genome, including the Y - chromosome contigs, to control for repetitive regions.

The Y - chromosome haplotype reconstructed for CGG10023 was distinct from those Y - chromosome haplotypes present in the modern horses, supporting previous hypotheses that domestication was associated with a significant loss of Y - chromosomal diversity (12, 26).
