13) Genetics
Thomson's gazelles have 58 chromosomes in both sexes (Nelson-Rees et al., 1967; Wurster & Benirschke, 1968). They lack the X/autosome translocation found in so many other African antilopinae (Effron et al., 1976).
A male hybrid with Gazella rufifrons was born in London but died the next day (Gray, 1972)
14) Immunology
I know of no immunological studies.
15) Pathological features
Trauma was found to be the commonest cause of mortality (Griner, 1983).
16) Physiologic data
No data are known to me.
17) Other resources
Cell strains of this gazelle species are available from CRES at San Diego zoo by contacting Dr. Oliver Ryder at: oryder@ucsd.edu.
18) Other remarks - What additional Information is needed?
No weights of mature placentas, nor have the lengths of their term gestation umbilical cords been recorded. Endocrine studies of gestation are needed.

The animal photographs in this chapter come from the Zoological Society of San Diego. I appreciate also very much the help of the pathologists at the San Diego Zoo.
