Examples of horse sex chromosome structural rearrangements (TAMUMCL archive). (A) Isochromosome Xq in a mare with short stature, no ovaries and 64,X,i(Xq) karyotype; (B) Trisomy Xq in a non-cycling mare with 65,XX,+Xq karyotype; (C) Complex dicentric X-autosome rearrangement in a mare with short stature but no other obvious problems, fertility unknown; (D) Sex chromosomes of three mares with SRY-neg XY male-to-female sex reversal syndrome; the first two have large deletions in the Y, the third one has a cytogenetically normal-looking Y, but a submicroscopic deletion around the SRY gene; (E) Partial Y chromosome deletion in a Shetland pony without penis (left, middle), comparison with the sex chromosomes of a normal male (right).
