The majority of homosporous ferns have a chromosome number that is severalfold greater than that of diploid seed plants. These fern species have therefore been generally considered to be of polyploid origin. Enzyme electrophoretic investigations have demonstrated, however, that within fern genera, species having the lowest chromosome numbers (n = 27-52) have the number of isozymes typical of diploid seed plants; there is no isozyme evidence for polyploidy of these plants. We have constructed a… CONTINUE READING
