Chromosomal Studies on Interspeciftic Hybrids of Butterflies Papilionidae, Lepidoptera)

Chromosomal studies on interspecific hybrids of butterflies (Papilionidae, Lepidoptera). IX. Crosses among P. machaon hippocrates, P. machaon gorganus, and P. polyxenes.

“…Hybridization experiments are of utmost importance in the evolution study of organisms. In former papers we dealt with the behavior of chromosomes during meiosis in male hybrids amongst P. polyctor, P, bianor, P. maackii, P. polytes, P, helenus, P. protenor, P. macilentus, P, paris, P. nepheles, P. aegeus, P. f uscus, P. memnon, P. ascalaphus, P. polymnestor, P. rumanzovia, P. machaon hippocrates, P. xuthus, P. benguetana, and P. polyxenes (Maeki and Ae 1964, 1966, 1970, 1975, 1976a, 1976b, 1976c, 1976d, 1977a. In the present article are furnished some cytogenetic data important for considering the phylogenetic relationship between the following three species belonging to the machaon-group, Papilio machaon gorganus commonly occurring over Europe, Papilio machaon hippocrates attaining prosperity in East Asia, and Papilio polyxenes having a wide distribution through the American Continent, major attention having been extended toward the meiotic behavior of hybrid chromosomes.…”

“…Hybridization experiments were responsible to Ae (1964Ae ( , 1965Ae ( , 1966Ae ( , 1967Ae ( ,1968 , and chromosome studies were carried out by Maeki according to the routine paraffin method. P. machaon gorganus was characterized by the chromosome number of n, 30 (Lorkovic 1941, Maeki 1976).…”
