Tritiated-thymidine autoradiography was used to follow the progress of cells through spermatogenesis in the axolotl, Ambystoma mexicanum. Results indicate that, at 18"C, the most rapidly maturing germ cells spend 5 days in leptotene, 5 days in zygotene, 22 days in pachytene, 1 day in diplotene, 6 da

## Abstract Gynogenetic haploids of the Mexican axolotl, __Ambystoma mexicanum__, were produced by artificial insemination of eggs with ultraviolet‐irradiated sperm. Initially, haploids developed more rapidly than control diploids, and had twice the number of cells by 12 hours. Thereafter, developm

In the Mexican axolotl, Ambystoma mexicanum, the developmental mutation lethal t is inherited as a simple Mendelian recessive. Mutant larvae failed to feed and died, on the average, 17 days after hatching. Unfed wild-type larvae died an average of 23 days after hatching. By 15 days, forelimb develop

## Abstract The development of pigment pattern in the eyeless mutant of __Ambystoma mexicanum__ is described. Pigmentation, is much enhanced in this mutant through increased size and branching of melanophores. The eyeless mutant does not possess the ability to adapt to its background, nor does it b

## Abstract We have re‐examined some of the factors affecting the induction of heart‐forming mesodern in the axolotl. The formation of functional, rhythmically contracting myocardial tissue was used as an assay. We have found that heart‐forming mesoderm is fully induced and capable of completing it
