Satellite DNA amounts were examined in adult tissues of Drosophila virilis, a species whose DNA contains three prominent satellites. Satellite amounts in DNA from six of the seven tissues were lower than in DNA from diploid (adult brain) tissue. Satellite amounts in adult ovary DNA, however, were equivalent to or greater than diploid levels. When DNA from pupal ovaries was examined, a 30% increase in satellite amounts over diploid levels was found. An RNA-DNA hybridization experiment showed that the ribosomal RNA genes in pupal ovary DNA were under-replicated relative to diploid DNA levels.
对果蝇（一种其DNA包含三种显著卫星DNA的物种）成虫组织中的卫星DNA含量进行了检测。七个组织中有六个组织的DNA中的卫星DNA含量低于二倍体（成虫脑）组织DNA中的含量。然而，成虫卵巢DNA中的卫星DNA含量与二倍体水平相当或更高。当检测蛹期卵巢的DNA时，发现其卫星DNA含量比二倍体水平增加了30%。一项RNA-DNA杂交实验表明，蛹期卵巢DNA中的核糖体RNA基因相对于二倍体DNA水平复制不足。
