限制性片段长度多态性（RFLPs）被用来作为标记，以监测线粒体遗传的细胞黏菌，梅毒螺旋体。当两个相反的交配型（mat1和mat2）的密切相关的菌株杂交，所有的单倍体后代，无论交配型继承他们的线粒体DNA从mat2的父母。当来自亲缘关系较远的菌株的相反交配类型杂交时，大多数后代也从mat2亲本遗传了线粒体DNA，但有些后代从mat1亲本遗传了线粒体DNA。然而，在这两种情况下，线粒体DNA的传递都是单亲的，因为在每一个单独的后代中只存在一种类型的线粒体DNA。此外，在涉及更远的相关菌株的杂交中，单个大孢囊的所有后代都含有相同类型的线粒体DNA。这些研究结果进行了讨论方面的传输机制和可能参与的核基因在控制的线粒体DNA的传输Polysphondylosis。
Restriction fragment length polymorphisms (RFLPs) were used as markers to monitor mitochondrial inheritance in the cellular slime mold, Polysphondylium pallidum. When two opposite mating types (mat1 and mat2) of closely related strains were crossed, all the haploid progeny regardless of mating type inherited their mitochondrial DNA from the mat2 parent only. When opposite mating types from more distantly related strains were crossed, most of the progeny also inherited their mitochondrial DNA from the mat2 parent, but some inherited their mitochondrial DNA from the mat1 parent. In both cases however, the transmission of mitochondrial DNA was uniparental, since in every individual progeny only one type of mitochondrial DNA exists. Moreover, in crosses involving more distantly related strains all the progeny of a single macrocyst were shown to contain the same type of mitochondrial DNA. These findings are discussed in regard to mechanisms of transmission and the possible involvement of nuclear genes in the control of transmission of mitochondrial DNA in Polysphondylium.
