Pa. Ramsay et al., Chorionic villus sampling for sex determination in a western lowland gorilla (Gorilla gorilla gorilla), J ZOO WILD, 31(4), 2000, pp. 532-538
Chorionic villus sampling was undertaken on an anesthetized gorilla (Gorill
a gorilla gorilla) to determine the fetal sex in the first trimester of pre
gnancy. The tissue samples were subject to sex determination by polymerase
chain reaction, fluorescent in situ hybridization, and cell culture with cy
togenetic analysis. Polymerase chain reaction testing was found to be the m
ost accurate and rapid method of sex determination on this tissue sample.
