Y-STR Statistical Analysis
As a result of these factors, the degree of inter-individual Y-chromosome variation is substantially reduced compared to the autosomes.
- A typical autosomal STR profile may have an expected frequency of occurence in 1 in every 100 trillion individuals (10-14), whereas a typical Y- STR profile may occur in 1 in every 1000 individuals (10-3).
