1990) induced gynogenetic diploids in Haliotis discus hannai by cold shock treatment of zygotes after insemination with UV-irradiated sperm, which resulted in 50% to 60% gynogenetic diploid in 6-too-old individuals proved by the analyses of isozyme genotypes.
The third group was the gynogenetic diploid group (G-2n group), in which gynogenetically activated eggs were treated with CB for chromosome doubling.
Production of Gynogenetic Diploid and Normal Triploid
Triploids, tetraploids, and aneuploids produced in the gynogenetic diploid group were reported also for the Pacific oyster (Guo et al.
Induction of gynogenetic diploid by inhibiting second meiosis in the pacific abalone.
A preliminary study on the induction of gynogenetic diploid and "Hertwig effect" in pearl oyster Pinctada martensii.
ABSTRACT The conditions for induction of gynogentic haploids and restoration of gynogenetic diploids, were studied in the small abalone, Haliotis diversicolor supertexta.
Gynogenetic diploids can be obtained by first using chromosome inactivated sperm to fertilize normal eggs and then suppressing the first or second meiotic division of these eggs or the first mitotic division of the zygotes.
Therefore, the purpose of this work is to establish the procedure to induce gynogenetic diploids in the small abalone.
