Growth and male ornamentation in Xiphophorus montezumae
Juvenile growth rate is an important life-history trait that affects the size at maturity, and may influence the development of sexual ornamentation. The sword of several species of the genus Xiphophorus (Teleostei: Poeciliidae) is an elaborate secondary sexual trait that confers an advantage in terms of sexual selection, counterbalanced by locomotive and predatory costs. This study assesses di...
متن کاملSpontaneous thyroidal tumors in the Swordtail Xiphophorus montezumae.
Early studies of the thyroid tumors of trout (3—5)have demonstrated the relationship between iodine supply and hyperplastic growth of thyroid cells. Experimental work with fishes provided much of the background for the present under standing of the etiology of human goiters. In con trast with encapsulated mammalian goiters, how ever, hyperplastic thyroids in fishes are remark able for their i...
متن کاملProgressive growth stages in the development of spontaneous thyroid tumors in inbred swordtails Xiphophorus montezumae.
Almost 50 years ago Gaylord and Marsh (5) and Marine and Lenhart (11, 12) showed that thyroid tumors in hatchery-reared trout developed from hypertrophied and hyperplastic thyroid tis sue. The tumors invaded and replaced muscle and bone; one tumor metastasized to the wall of the rectum. Gaylord and Marsh classified the tumor as a carcinoma, but Marine and Lenhart regarded it as a severe endemic...
متن کاملEvolution of a genetic incompatibility in the genus Xiphophorus.
Genetic incompatibilities are commonly observed between hybridizing species. Although this type of isolating mechanism has received considerable attention, we have few examples describing how genetic incompatibilities evolve. We investigated the evolution of two loci involved in a classic example of a Bateson-Dobzhansky-Muller (BDM) incompatibility in Xiphophorus, a genus of freshwater fishes f...
متن کاملHomology of melanoma-inducing loci in the genus Xiphophorus.
Several species of the genus Xiphophorus are polymorphic for specific pigment patterns. Some of these give rise to malignant melanoma following the appropriate crossings. For one of these pattern loci from the playfish Xiphophorus maculatus the melanoma-inducing gene has been cloned and found to encode a novel receptor tyrosine kinase, designated Xmrk. Using molecular probes from this gene in S...
