TL;DR: In this article, the existence and properties of maximal connected topologies are investigated. But they do not consider the case where the set X is a set X with topology, and X is connected if (X, ) is a connected topological space.
Abstract: If (X, ) is a set X with topology we shall say that is connected if (X, ) is a connected topological space. We shall investigate the existence of and the properties of maximal connected topologies.

TL;DR: Various types of testicular abnormalities, encountered in deep orange Drosophila melanogaster males, have been described and the occurrence of a relatively high incidence of abnormalities among males bearing an X-chromosome balancer (FM4) is reported.
Abstract: Various types of testicular abnormalities, encountered in deep orange (dor) Drosophila melanogaster males, have been described. These abnormalities range from complete failure of attachment and, therefore, of elongation and coiling of both testes, to attachment and partial elongation of one testis. The frequency of testicular dysgenesis among affected lines can be readily modified by varying the culture conditions or the genetic background. The occurrence of a relatively high incidence of abnormalities among males bearing an X-chromosome balancer (FM4) is reported.
