MANY data exist on natural and induced polyploidy in Amphibia1,2; but knowledge on the subject still remains scanty in other groups of vertebrates. Spontaneous and experimentally produced polyploidy has been studied in mouse embryos3–7. Among fishes, production of triploidy by cold treatment has been reported up to cleavage stages8. The present work has been undertaken to induce triploidy by heat and cold treatment of the eggs of the three-spined stickleback and to keep alive the triploids thus… 
An experiment on induction of triploidy inEriocheir japonicus hepuensis Dai by heat treatment
Temperature treatment to inhibit extrusion of the polar body of the egg was first used on a lower crustacean,Artemia salina (Gross, 1932), and then was used for inducing triploids of amphibian
The oxygen consumption of diploid and triploidGasterosteus aculeatus (L)
TLDR
Oxygen consumption of the triploidGasterosteus aculeatus and their diploid controls has been determined by Winkler's method and the difference in the rate of respiration of triploids and diploids fish is significant if calculated per unit area of body surface.
Induction of diploid gynogenesis in an evolutionary model organism, the three-spined stickleback (Gasterosteus aculeatus)
TLDR
The first successful induction of diploid gynogenesis in an evolutionary model system, the three-spined sticklebacks (Gasterosteusaculeatus), using a combination of UV-irradiation of the sperm and heat shock of the resulting embryo to inhibit the second meiotic division is presented.
Effect of triploidy on the body size, general organization and cellular structure inGasterosteus aculeatus (L)
Summary1. In experimentally produced triploidGasterosteus aculeatus, the body size is similar to that of the normal diploid forms, but the proportions of the trunk and tail to the body size are
Why are triploid zebrafish all male?
TLDR
It is suggested that triploidy inhibits development of oocytes past the primary growth stage, and this causes female to male sex reversal.
Experimental production of triploid brown trout, Salmo trutta L., using heat shock
TLDR
The highest triploid yield was produced with a heat shock of 28°C for 10 min initiated at 10 or 20 min post-insemination, the difference between replicates being due to variability in survival to hatch.
Diploid gynogenesis in Xenopus laevis and the localization with respect to the centromere of the gene for periodic albinism ap.
TLDR
It is very probable that the relatively high mortality or abnormal development obtained with the pressurized eggs is not due to partial homozygosity but rather to physical damage to the egg structure by this treatment.

Colchicine-induced Heteroploidy in Early Mouse Embryos
TLDR
The heteroploid status of the mature rabbit and boar has, however, been disputed by several workers, for example, Beatty and Fischberg8.
Spontaneous and Induced Triploidy in Pre-Implantation Mouse Eggs
TLDR
It would be of interest to extend the study of polyploidy to mammals to throw light on such important problems as physiological genetics, with special reference to dominance and gene dosage effects in vertebrates.
HETEROPLOIDY IN MOUSE EMBRYOS DUE TO CROSSING OF INBRED STRAINS
TLDR
The present work was undertaken to answer the following questions: is the high incidence of heteroploid eggs in the cross of silver females to males of other strains, and also b) crossing of different strains, involving perhaps an incompatibility between the eggs ofsilver females and the sperm of non-silver males.
