Хромосомный гетероморфизм Octolasium lacteum (Oerley, 1885) (Oligochaeta, Lumbricidae) как результат гибридогенеза

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Karyotype Octolasium lacteum (Oerley, 1885) is studied. The chromosomal formula is 2n =
= 13m+23sm+2st = 38; the fundamental number is FN = 76; and the total diploid complement
length is TCL = 176.91±14.22 µm. The heteromorphism of the first chromosome pair which is
represented by a large submetacentric and a smaller metacentric is discovered. Spermatogonial
meiosis of this species has some violations. Only 12 bivalents (at n = 19) are discovered. The
karyotype of this species is supposed to appear as a result of hybridization of the related species
with the chromosome numbers 2n = 36 and 2n = 40. |
