High diversity of structurally heterozygous karyotypes and rDNA arrays in parthenogenetic aphids of the genus Trama (Aphididae: Lachninae).

Heredity - 1 Feb 2000

Blackman R L, Spence J M, Normark B B

Abstract excerpt

Karyotypes of permanently parthenogenetic aphids of three species of the genus Trama show great diversity, particularly in the number and distribution of chromosomal elements containing highly repetitive sequences. Sampling at only a few sites in southern England, chromosome number varied from 14 to 23 in T. troglodytes, 9-12 in T. caudata and 10-14 in T. maritima, with some colonies having individuals of more...
