Maximum likelihood inference implies a high, not a low, ancestral haploid chromosome number in Araceae, with a critique of the bias introduced by 'x'.

Annals of botany - 1 Mar 2012

Cusimano Natalie, Sousa Aretuza, Renner Susanne S

Abstract excerpt

BACKGROUND AND AIMS: For 84 years, botanists have relied on calculating the highest common factor for series of haploid chromosome numbers to arrive at a so-called basic number, x. This was done without consistent (reproducible) reference to species relationships and frequencies of different numbers in a clade. Likelihood models that treat polyploidy, chromosome fusion and fission as events with particular...
