The amelogenin gene has been most widely studied in humans, where it is a single copy gene, located on the X and Y chromosomes at Xp22.1–Xp22.3 and Yp 11.2 [5]. [3] The amelogenin gene's location on sex chromosomes has implications for variability both between the X chromosome form and the Y chromosome form (), and between alleles of AMELY among different populations.
Paternally-derived chromosome rearrangement psu dic: pseudo dicentric – only one centromere in a dicentric chromosome is active q: Long arm of a chromosome r: Ring chromosome t: Translocation: ter: Terminal end of arm (e.g. 2qter refers to the end of the long arm of chromosome 2) tri: Trisomy: trp: Triplication of a portion of a chromosome
A mechanism of sex determination that depends upon the ratio of the number of X chromosomes (X) to the number of sets of autosomes (A). Males develop when the X/A ratio is 0.5 or less, females when it is 1.0 or more, and an intersex develops when it is between 0.5 and 1.0. [8] genic selection

For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y chromosome. Since 2010, scientists have known that the Y chromosome is rapidly ...
PAR1 comprises 2.6 Mbp of the short-arm tips of both X and Y chromosomes in humans and great apes (X and Y are 154 Mbp and 62 Mbp in total). PAR2 is at the tips of the long arms, spanning 320 kbp. [5] The monotremes, including the platypus and echidna, have a multiple sex chromosome system, and consequently have 8 pseudoautosomal regions. [6]

Three chromosomal abnormalities with ISCN nomenclature, with increasing complexity: (A) A tumour karyotype in a male with loss of the Y chromosome, (B) Prader–Willi Syndrome i.e. deletion in the 15q11-q12 region and (C) an arbitrary karyotype that involves a variety of autosomal and allosomal abnormalities.
