Statistical Expert Testimony

In criminal cases, our team has great expertise in analyzing:

1. Y-STR

Y-STR is a short tandem repeat (STR) on the Y-chromosome. Y-STRs are often used in forensics, paternity, and genealogical DNA testin.Y-STRs are taken specifically from the male Y chromosome. These Y-STRs provide a weaker analysis than autosomal STRs because the Y chromosome is only found in males, which are only passed down by the father, making the Y chromosome in any paternal line practically identical. This causes a significantly smaller amount of distinction between Y-STR samples. Autosomal STRs provide a much stronger analytical power because of the random matching that occurs between pairs of chromosomes during the zygote making process.

2. MITOCHANDRIAL

In multi-cellular organisms, mtDNA is inherited from the mother (maternally inherited). Mechanisms for this include simple dilution (an egg contains on average 200,000 mtDNA molecules, whereas a healthy human sperm was reported to contain on average 5 molecules, degradation of sperm mtDNA in the male genital tract, in the fertilized egg, and, at least in a few organisms, failure of sperm mtDNA to enter the egg. Whatever the mechanism, this single parent  ( uni-parental inheritance)pattern of mtDNA inheritance is found in most animals, most plants and in fungi as well.

3. AUTOSOMAL DNA

Autosomal DNA is inherited form both parents. Autosomal DNA test may be taken buy either a male or a female. Short tandem repeat (STR) markers on the autosomal chromosomes havebeen used  in academic population genetics studies and for extended forensic and sibling studies.

 

In civil cases, our team has great expertise in:
