An Idiogram Study of the Chromosomes in Some Species of Reptiles

Abstract

The chromosomes of ten species of reptiles were investigated in male germ cells through spermatogenesis, with special regard to the karyotype. Table 2 gives the chromosome relationship in the species under study which are arranged in systematic order. By way of summary it may be said that the chromosomal relation of reptiles is on the whole closely related within the genus, but it seems not the same with the family, since a family includes various karyotypes considerably different in the chromosome constitution. © 1949, Japan Mendel Society, International Society of Cytology.
