The heterothallic, unicellular green alga Chlamydomonas reinhardi possesses both chromosomal and nonchromosomal systems of inheritance. Mutations belonging to the latter system are capable of recombination. The experiments reported show that double and triple recombinants can be obtained from crosses employing three phenotypically distinct mutations and that certain pairs of mutants recombine more freely than others.
异宗配合的单细胞绿藻莱茵衣藻具有染色体遗传系统和非染色体遗传系统。属于后一种系统的突变能够发生重组。所报道的实验表明，利用三个表型不同的突变进行杂交可以获得双重组体和三重组体，而且某些突变对之间的重组比其他突变对更自由。
