Gynogenesis is a way of Sexual reproduction to produced desired offspring only with the help of maternal gametes. Disabled sperm was used to fertilize the maternal egg to produce the progeny. Genetic material of sperm was ruined by using certain radiation like UV or X-rays. Concentration and the exposure duration of radiation were very important to disabled the sperm. After the fertilization of the egg with the deactivated sperm the main focus is on the restoration of diploidy which was achieved by applying shock treatment to the eggs. While the induction rate of gynogenesis was comprised of 90-100% but the survival rate of the progeny was mot maximum because it differs in various species due to certain factors like shock type, time of exposure and size of the organisms. Beneficial results have been shown in fish breeding to obtain maximum number of female progeny. This method was adopted to obtain monosex population to meet desired demand. The resultant progeny which were obtained from gynogenesis method was haploid in number.Pages: 282-285 | 170 Views 16 DownloadsDownload Full Article:
