|Genetic mapping information|
|Comments on Cytology|
Chromosome J-shaped in metaphase <up>e.g., Janning, 1970, Mol. Gen. Genet. 107: 150-57 (fig.)</up>. An X chromosome in normal sequence with YS appended as a second arm. May carry varying amounts of the proximal part of YL between X and the centromere.

Males carrying X.YS require KL in some form for fertility.

|Notes on Origin|
Recurrent product of recombination the proximal heterochromatin of C(1)RM and the Y Also recovered as one element of T(1;Y)'s induced in X/Y sperm with one break in YL and the other in X heterochromatin (Kennison, 1981, Genetics 98: 529-48).
