(^1) All species investigated karyologically so far are listed: the DNA content values for all species studied are given.
(^2) Determined by flow cytometry.
(^3) Chromosome number is assumed onthe basis of the DNA content.
(^4) Determined by microdensitometry of Feulgen-stained nuclei.
(^5) Only macrochromosomes were counted precisely.
(^6) Determined by the biochemical Schmidt-Thankauser method.
(^7) Chromosome number was determined in cardiac tissue cell culture.
(^8) Chromosome number was determined in cell cultures: the modal 2n in a spleen cell line was 219, and in a heart cell line, 237–243 (Hedrick
et al. 1991).
