Abstract
Placental mammals have numbers generally more than double those found in marsupials, but less than those found in ungulates. All primates studied have the same chromosome number except a brown Cebus monkey which has 54. The possibility of man''s number being a secondary tetraploid number may explain occurrence of intersexes, since intersexes frequently occur in tetraploids. Presence of extra nucleoli which arise through polyploidy may prove useful in phylogenetic studies in mammals.This publication has 4 references indexed in Scilit:
