What is a Y STR DNA Test?
At-Home Y STR DNA Test Kit
Y Chromosome DNA Test is a test to determine whether two males are biologically related through their paternal line.
Every male on the planet has a Y chromosome. The Y Chromosome is passed down from father to son untouched. The circumstance in which a man may want to perform this type of DNA test occurs when the biological father is unavailable to be tested.
If the alleged father’s parents and siblings are unavailable to be tested and, the male child has a male cousin from his alleged uncle (father’s biological brother who shares the same father). Then the Y STR (Short Random Repeat) DNA test would be an excellent option to support the probability of a biological relationship when no other family reconstruction DNA test can be performed.
It should be noted, this type of DNA test can only prove biological relatedness and not actual relationships. For example, this test cannot definitively show if two men are siblings. What it can help determine as stated earlier is that the two men share the same paternal line.
The results for this testing option cannot be used for any legal purposes.

Legal Y STR DNA Test
Y-Chromosome DNA testing, often referred to as a male lineage test, is a genetic testing method used to establish a direct paternal line.
This type of DNA test focuses on the Y chromosome, which is passed down from father to son virtually unchanged. Since only males carry a Y chromosome, this test is specific to determining male ancestry and can be a powerful tool in legal cases where paternity needs to be established or verified.
When a Y-Chromosome DNA test is conducted for legal purposes, such as in child support disputes, social security benefits, inheritance claims, or child custody cases, it must follow a strict chain of custody to be admissible in court.
This means that the test must be conducted by an accredited laboratory, with the sample collection and handling being documented and certified by a third-party to ensure that the samples have not been tampered with.

Related Questions
Is Y Chromosome identical between a father and sons?
The Y chromosome is passed down from father to son largely unchanged, so it is nearly identical between a father and his sons. However, small changes, known as mutations, can occur during DNA replication when the chromosomes are passed on.
These mutations are generally rare, so the Y chromosome remains a consistent marker for patrilineal inheritance and can be used in genetic studies tracing male lineage. Despite the high degree of similarity, it is not absolutely identical in every single case due to the potential for these mutations.
