“…Fertilization with y-irradiated sperm is a good way, in salmonids, to obtain a large number of haploid embryos (Purdom, 1969 ;Chourrout et al, 1980) ; these embryos reach a late stage of organogenesis but generally die before, or immediately after, hatching.…”

“…Diploid gynogenesis was recently induced in several fish species by using cold shocks (more than 1 hr at less than 4°C) beginning a few minutes after fertilization with irradiated sperm (Romashov et al, 1963 ;Purdom, 1969 ; Nagy et at., 1978).…”

“…Gynogenesis has been widely used in different genetic experiments, in studies of karyotypes (Parmenter, 1925(Parmenter, , 1933Kawamura, 1939;Svärdson, 1945), for chromosome mapping (Nace 81 al., 1970;Volpe, 1970;Purdom, et al, 1976), for establishing inbred strains (Nace, 1968;Purdom, 1969;Stanley and Sneed, 1973;Nagy et al, 1978), and in studies of mutagenesis (Metzger-Freed, 1972). In most of these studies amphibians were used.…”

Genetic analysis in carp (Cyprinus carpio) using gynogenesis

et al. 1979

SUMMARYThe present paper reports the utilisation of gynogenesis irs genetic analysis and chromosome mapping in carp. A new colour mutant was analysed with the help of gynogenetic haploid, diploid and biparental F1 and F2 populations. The mutant character was controlled by two genes, P and R, and only fish with double recessive alleles pprr showed the mutant coloration. The genekinetochore (G-K) distances of the genes were established. G-K distances were measured for two other genes-transferrin and scaliness.

Production and propagation of fully inbred clonal lines in the Nile tilapia (Oreochromis niloticus L.)

et al. 1999

Fully inbred clonal lines of fish are likely to be of great value in research on immunology, sex determination, quantitative genetics, and toxicology. In this study on the Nile tilapia (Oreochromis niloticus), gynogenesis or androgenesis were used to produce a first generation of completely inbred fish, from which clonal lines were established using gynogenesis, androgenesis, hormonal sex reversal and intraline crosses. The clonal nature of these lines was verified by using multilocus DNA fingerprinting and the isozyme locus ADA*. Although these lines might be expected to be monosex in nature (all‐female XX or all‐male YY depending on the clone), one line did contain both sexes of fish. The presence of males in this gynogenetic clonal line and data from progeny testing of these males suggested that this line was homozygous for an allele or combination of alleles at an autosomal locus or loci which caused female to male sex reversal but with limited penetrance. Outbred clonal lines were also produced by crossing between different inbred clones. J. Exp. Zool. 284:675–685, 1999. © 1999 Wiley‐Liss, Inc.
