In humans, the SRY gene is located on short (p) arm of the Y chromosome at position 11.2. Sex-determining region Y protein (SRY), or testis-determining factor (TDF), is a DNA-binding protein (also known as gene-regulatory protein/transcription factor) encoded by the SRY gene that is responsible for the initiation of male sex determination in therian mammals (placentals and marsupials). [5]
The Y chromosome is one of two sex chromosomes in therian mammals and other organisms.Along with the X chromosome, it is part of the XY sex-determination system, in which the Y is the sex-determining chromosome because the presence of the Y chromosome causes offspring produced in sexual reproduction to be of male sex.
SOX genes (SRY-related HMG-box genes) encode a family of transcription factors that bind to the minor groove in DNA, and belong to a super-family of genes characterized by a homologous sequence called the HMG-box (for high mobility group). This HMG box is a DNA binding domain that is highly conserved throughout eukaryotic species.
Hairy ears are an example of a gene once thought to be Y-linked in humans; however, that hypothesis was discredited. [5] Due to advancements in DNA sequencing, Y linkage is getting easier to determine and prove. The Y-chromosome has been entirely mapped, [7] revealing many Y-linked traits. [8]
Once the SRY gene is activated, cells create testosterone and anti-müllerian hormone which typically ensures the development of a single, male reproductive system. [9] In typical XX embryos, cells secrete estrogen, which drives the body toward the female pathway. In Y-centered sex determination, the SRY gene is the main gene in determining ...

There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.
