A Form of Intersexuality

A widespread and distinctive form of amphipod intersexuality not induced by known feminising parasites.

Intersexuality occurs in a diverse range of animals, and its study offers insights into basic reproductive biology. Investigations in amphipods suggest intersexuality results from incomplete feminisation caused by sex-distorting parasites. It has also been noted that 2 intersex phenotypes occur in males of the amphipod Echinogammarus marinus, an external phenotype, in which males possess rudime...

A Study of Intersexuality in Drosophila Virilis.

N THIS paper a detailed account of our study of intersexuality in DroI sophila virilis will be given. The progress of this work has been reported elsewhere (LEBEDEFF 1934a and b, 1938a and b). These intersexes are the result of mutative changes within the normal diploid system, and they differ from intersexes in other species genetically, morphologically and embryologically. Intersexes in Lyman...

A New Type of Mammalian Intersexuality

IN 1922, while investigating the fauna of the New Hebrides under the Percy Sladen Trust, I found that many of the domestic pigs (Suspapuensis Less, and Garn.) kept by the natives were intersexual. These monstrosities had previously been noticed by anthropologists (Codrington, 1891). I dissected one of them and found that it differed from the great majority of the intersex pigs and goats occasio...
