“…Conversely, Scr duplications increase the number of sex comb teeth (Capdevila et al 1986; Kennison and Russell 1987; Boube et al 1997). Moreover, gain-of-function mutations that cause ectopic expression of Scr in T2 and T3 legs are sufficient to induce ectopic sex combs in these legs (Hannah-Alava 1964; Kaufman et al 1980; Kennison and Tamkun 1988; Pattatucci and Kaufman 1991). Analysis of temperature-sensitive Scr alleles indicates that Scr is required for sex comb development during late third larval instar and early pupal development (Pattatucci et al 1991).…”

“…Mutant genes that change the chaetotaxal patterns of the second and third pairs of legs of Drosophila to the direction of the first legs are collectively called "extra-sexcomb" mutants (HANNAH and STROMNAES 1955;HANNAH-ALAVA 1969) inasmuch as one of the most obvious phenotypic effects common to all of them is the presence, in the metatarsae of the hind legs of males, of one or more chaetae similar to the chaetae constituting the normal sex comb of the male foreleg. Three different genes, Pc (Polycomb), Scx (Extra sex comb), and Msc (Multiple sex comb) with one or two mutant alleles at each locus have been identified in the third chromosome of Drosophila melanogaster.…”

“…Attention has been paid to the fact that all three "extra-sexcomb" genes in the third chromosome are located at about 47.5 in the genetic map (HANNAH-ALAVA 1969;DENELL 1973;POSTLETH-WAIT and SCHNEIDERMAN 1973). This has been regarded as a possible indication that they were derived from a single ancestor by a tandem duplication and, consequently, might share part of a common function.…”
