✦ Synopsis

Abstract

Spongilla lacustris exhibits a type of alternative hermaphroditism, new to the phylum, in which a sponge may be exclusively male or female during the period of sexual reproduction one year and the opposite sex the next year. This form of sexuality may facilitate larva production and thus dispersal following colonization of a new habitat. Gametogenesis occurs shortly after gemmule hatching in both males and females but slightly later in males.

We present evidence that the inbred mouse strain C57BL16J (B6) differs from Mus domesticus (DOM) at a locus involved in gonad determination and development as well as at the testis-determining locus on the Y chromosome (Tdy). This newly identified gene is named testis-determining, autosomal-1 (tda-1
