Permanent translocation heterozygosity in dioecious Baccharis coridifolia DC. (Asteraceae)

Mostrar todas las versiones(3)

The karyotype of Baccharis coridifolia DC., a dioecious diploid species consists of 16 chromosomes with median (m) and 2 with submedian centromeric positions (sm) (2n = 18). Meiotic analyses of 219 male plants belonging to 12 populations showed across a wide geographical range one quadrivalent and s...
