Dormancy and germination of heteromorphic
achenes of Bidens frondosa.
The complement includes 10 bi-armed, 12 acrocentric pairs of autosomes and, occasionally, one heteromorphic
(subtelocentric/acrocentric) large autosomal pair.
In Canscora roxburghii, corolla and androecium (heteromorphic
anthers) are monosymmetric (Thiv & Kadereit, 2002b).
The structures were identified as heteromorphic
deutonymphs of Hypodectes propus (Order Astigmata) of the family Hypoderatidae.
sex chromosomes were found in Schizothorax esocinus.
indica (Schumann, 1886; Scott, 1978; Verdoorn, 1981; Thulin, 1998) were: cymes heteromorphic
, calyces unorderly, half (Scott, 1978) to none (Scott, 1978; Thulin, 1998) of the normal nearly completely fused stamen filament fusion lengths, a stipitate distended arcuate pistil, ovary abnormally shaped and stigma composite-nodular.
2010)] in males, and other own observation (in Sutton's slides) that some individuals carried a heteromorphic
autosomal pair: thus, both homologues could be microscopically identified according to size (Carothers 1913).
First, when one sees a liverwort, hornwort, or moss in the field or elsewhere, the observed specimen, with only a very few exceptions, represents the gametophyte (1n) phase of the organism's heteromorphic
alternation of phases (or generations).
Meiotic complements of the three analyzed species of the family Bothriuridae contain no heteromorphic
chromosome pair, which indicates the absence of heteromorphic
sex chromosomes in males, as is also the case in Buthus occitanus (Amoreux 1789) and Pandinus imperator (C.L.
Aquatic or amphibious, stems creeping with adventitious roots from nodes and internodes; leaves heteromorphic
(photosynthetic and fertile), petioles filiform, blades palmately divided into 4 pinnae; sporocarps horizontal to strongly ascending near base of petioles.
Definitive taxonomic identification of most damselfly species is based upon microscopic examination, particularly of genital anatomy, and the genus Ischnura is a notoriously difficult one since in many species females, and sometimes males, may be heterochromic and even heteromorphic
