Three genealogies are available. The first is a Microsoft Excel database of all animals that have contributed to the current gene pool. This genealogy lists date of birth, Acquisition number, house name, dam’s house name and number, sire’s house name and number, and AZA number. Animals currently in the collection are in boldface. The second, also in Excel, is a graphical representation of the matrilines arranged by year of birth. Printed, this file is about a meter wide, and is divided into two parts, up to 2006 and since that time. The third file is similar to the second, but by patrilines.
