Recombination with the Y chromosome leads to detachments with a frequency of about 10-3 in C(1)RM/Y females. Has been extensively used in studies of crossing over (e.g., Anderson, 1925, Genetics 10: 403-17; Beadle and Emerson, 1935, Genetics 20: 192-206; Welshons, 1955, Genetics 40: 918-36).

hide Notes on Origin
Discoverer
L. V. Morgan, 12th Feb. 1921.
 
Recurs regularly by exchange between the heterochromatin of the short arm of one X, XYS, or XYL that of the base of the long arm of a sister or homolog. Can be induced in mature X.YL -bearing sperm (Leigh, 1972, DIS 48: 107). Presumably the pericentric heterochromatic constitutions of independently arising C(1)RM chromosomes varies.
