... According to the pre-vious chromosomal reports, most species of the genus Bauhinia display a consistent chromosomal count of 2n=28 (Table 1). Somatic chromosome number 2n= 42 chromosomes in the somatic cells of B. monandra also reported earlier (Darlington and Wylie 1955). Based on prior data, the genus under examination typically possesses a monobasic chromosome number of x=14, with a predominantly somatic chromosome count of 2n=28 (Sharma and Raju 1968;Fedorov 1974;Kumar and Subramaniam 1987). ...
... Chromosomes in L. revoluta have median region, median point, submedian region, and subterminal region centromeres (Dixit et al. 1989;Haque and Ghosh 2016;Giranje et al. 2019). It shows active cytogenetical differentiation that is evident from the presence of various chromosome counts, i.e., n=9, 10, 11, 12, 13, 15, 16, 17, 22 (Jessop 1970, Sarkar et al. 1980Haque andGhosh 2016) and2n=20, 22, 28, 30, 44, 45, 46, 58, 60, 64, 68, 90 (Raghavan andVenkatasubban 1939;Sheriff and Murthy 1946;Rao 1953;Darlington and Wylie 1955;Rao 1956;Sen 1973;Jha and Sen 1980;Sheriff and Rao 1981;Subramanian 1981;Dixit et al. 1989;Stedje 1996;Johnson and Brandham 1997;Nair 1989;Sheeba and Vijayavalli 1998;Haque and Ghosh 2016;Giranje et al. 2019). ...
... Dicentric chromosomes can also be introduced by nondisjunction at meiosis after crossing-over within a heterozygous paracentric inversion. Dicentric BFB cycles originating in this way have been shown to persist for several years in Narcissus (Darlington and Wylie 1952) and Agropyron (Hair 1952 ). In each case, DCs differing in intercentromeric distance and monocentrics of varying morphology resulted from the BFB cycle. ...
