Y-STR analysis tips and case studies

  Toward male individualization with rapidly mutating y-chromosomal short tandem repeats
Rapidly mutating Y-STR loci can help discriminate between closely related male relatives. Learn more about them in this publication. Ballantyne KN, Ralf A, Aboukhalid R et al. (2014) Hum Mutat 35(8):1021-1032. doi: 10.1002/humu.22599. Epub 2014 Jul 14.

  Interpreting Y chromosome STR haplotype mixture
Assessment of mixtures from Y-STRs differs from traditional autosomal STRs, due to lack of recombination. Learn how to best augment your lab’s forensic insight with this capability.
Ge J, Budowle B, Chakraborty R (2010) Leg Med (Tokyo) 12(3):137-143. doi: 10.1016/j.legalmed.2010.02.003. Epub 2010 Mar 25.
