与D.黑腹果蝇有2个基因座，含有编码MW 70，000的主要热休克蛋白（hsp 70）的序列。这些序列排列为2对反向重复序列。对D.黑腹菌似乎是通过DNA插入而产生的。两个位点的Hsp70编码序列不是独立进化的。热休克蛋白70基因之间的基因转换显然既发生在基因座内，也发生在基因座之间。
Several species related to D. melanogaster have 2 loci containing sequences which code for the major heat-shock protein of MW 70,000 (hsp 70). These sequences are arranged as 2 pairs of inverted repeats. The structure of the 87C locus in D. melanogaster seemingly arose through DNA insertion. Hsp 70-coding sequences at the 2 loci are not evolving independently. Gene conversion between hsp 70 genes apparently occurred both within and between loci.
