Cleland's most seminal field of research concerned the genetics of the plant genus Oenothera.[1][2] He discovered the structures of linked rings of meiotic chromosomes (not to be confused with ring chromosomes)[3] that, by their interference with functions such as chromosomal crossover explained the unusual genetics and reproduction of plants in the genus Oenothera.[4][5]
