This special re-print edition of Detlefsen's book "Genetic Studies On A Cavy Species Cross" contains all the information a person needs to master the basics of raising Cavies or Guinea Pigs. Written in 1914, this book contains information gleaned from studies on the subject of Cavy genetics. The study involved crossing the species Cavia rufscens to Domestic Guinea Pigs and back-crossing their fertile female offspring to the parent species for successive generations. Subsequently, the inheritence of coat colors and other characteristics were studied. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface.
