Ancient polyploidy and low rate of chromosome loss explain the high chromosome numbers of homosporous ferns
Zheng Li, Sylvia P. Kinosian, Shing H. Zhan, Michael S. Barker
The paper tests the hypothesis that ancient polyploidy and low chromosome loss explain high chromosome numbers in ferns, finding similar paleopolyploidy rates but lower chromosome loss in ferns compared to angiosperms.
