The sperm length and the testis length in Drosophila nasuta snbgroup

Abstract

The species-specific sperm length and testis length were observed among the fourteen members of the Drosophila nasuta subgroup. The sperm length was highly correlated with the testis length and they reflected the taxonomic relationship. The present study suggests that the sperm length does not play an important role in the reproductive isolation in this subgroup. © 1986, The Genetics Society of Japan. All rights reserved.
