The genetic interval 35C to 36A on chromosome arm 2L of Drosophila melanogaster has been saturated for mutations with visible or lethal phenotypes. 38 loci have been characterized, including several maternal-effect lethals (vasa, Bic-C, chiffon, cactus and cornichon) and several early embryonic lethals, including snail and fizzy. About 130 deletions have been used to order these loci. Complex interactions between mutant alleles have been uncovered in the immediate genetic environs of the snail gene, as has further evidence for an interaction between this region and that including the nearby genes no-ocelli and elbow.
黑腹果蝇2号染色体左臂上从35C到36A的遗传区间已被具有可见或致死表型的突变所饱和。已鉴定出38个基因座,包括几个母性效应致死基因(瓦萨基因、双胸复合体基因、雪纺基因、仙人掌基因和黄瓜基因)以及几个早期胚胎致死基因,如蜗牛基因和模糊基因。大约130个缺失已被用于对这些基因座进行排序。在蜗牛基因的直接遗传环境中发现了突变等位基因之间的复杂相互作用,同时也有进一步证据表明该区域与包括附近的无眼基因和肘部基因的区域之间存在相互作用。
