The results were obtained by studying spreads prepared from bonemarrow biopsies taken while the animals were chemically immobilized. 33 good spreads were examined prepared from 1 male and 1 female and is supported by counts of leukocyte cultures.
The chromosome number is found to be 2n = 82.
This is the highest figure yet obtained from any mammal.
The karyotype of the white rhino shows group I to consist of 8 submetacentric pairs and group II of 32 acrocentric chromosome pairs with a large metacentric X- and a small acrocentric Y chromosome.
