ABSTRACT The conditions for induction of gynogentic haploids and restoration of gynogenetic diploids, were studied in the small abalone, Haliotis diversicolor supertexta. Gynogentic diploids were produced by first using chromosome inactivated sperm to fertilize normal eggs and then suppressing the second meiotic division of these eggs. Sperm chromosomes were effectively inactivated with UV irradiation for 50-90 sec at an intensity of 1075 [micro]W [cm.sup.2] x [s.sup.-1]. The decre...
