What do you need to know about Y-Chromosome DNA testing?
The Y-Chromosome is only found in males and is passed on from a father to his sons. It can be used to trace clearly a direct paternal line. There are two types of Y-Chromosome DNA Testing, short tandem repeat (STR) and single nucleotide polymorphism (SNP).
The STR test is considered best for recent ancestry while SNP tests can tell about more ancient ancestry. The DNA testing professionals find STRs very useful in verifying common ancestry between two males and finding genetic cousins on the paternal line.
Apart from ancestry, in a forensic DNA analysis, the male-specific part of the human Y chromosome is widely used. Mainly in cases where standard autosomal DNA profiling is ineffective, the Y-Chromosome DNA testing is a good choice. A Y-chromosomal gene fragment is used for deducing the biological sex of a crime scene trace donor.
