=== Lily and mouse ===

The lily is a favored organism for the cytological examination of meiosis since the chromosomes are large and each morphological stage of meiosis can be easily identified microscopically. Hotta, [[Ann Chester Chandley|Chandley]] et al.<ref name="pmid593319">{{cite journal |last1=Hotta |first1=Yasuo |last2=Chandley |first2=Ann C. |last3=Stern |first3=Herbert |title=Meiotic crossing-over in lily and mouse |journal=Nature |date=September 1977 |volume=269 |issue=5625 |pages=240–242 |doi=10.1038/269240a0 |pmid=593319 |bibcode=1977Natur.269..240H |s2cid=4268089 }}</ref> presented the evidence for a common pattern of DNA nicking and repair synthesis in male meiotic cells of lilies and rodents during the zygotene–pachytene stages of meiosis when crossing over was presumed to occur.  The presence of a common pattern between organisms as phylogenetically distant as lily and mouse led the authors to conclude that the organization for meiotic crossing-over in at least higher eukaryotes is probably universal in distribution.{{cn|date=February 2024}}
