A CURRENT LIST OF CHROMOSOME NUMBERS AND VARIATIONS FOR SPECIES OF AVIAN SUBCLASS CARINATAE

SINCE the earlier reviews by Makino12 and Brant8 of chromosome numbers in birds, technical advances have revolutionized avian cytology. This development has given new impetus to attempts to resolve long standing questions. la 1965, Shoffner14 identified several areas of ayian cytogenetics that were clearly deficient: These included knowledge of chromosome numbers, constancy of meiotic and mitotic division producte (particularly regarding the smaller chromosomes), sex chromosomes, and chromosome variations. © 1969, Oxford University Press.
