comparative karyotype analysis of two iranian cyprinids, alburnoides bipunctatus and alburnus filippii (cypriniformes, cyprinidae)
found in iran, alburnoides bipunctatus and alburnus filippii. the chromosomes of these species were compared using giemsa staining and silver-staining (ag) techniques to describe the karyotypes. both species possess 2n = 50 chromosomes with no detected sex heteromorphism. the karyotypes were distinct, composed of 7 pairs of metacentric, 10 pairs of submetacentric, and 8 pairs of subtelo-acrocen...
متن کاملKaryotype differentiation between two stickleback species (Gasterosteidae).
The stickleback family (Gasterosteidae) of fish is less than 40 million years old, yet stickleback species have diverged in both diploid chromosome number (2n) and morphology. We used comparative fluorescence in situ hybridization (FISH) on 2 stickleback species, Gasterosteus aculeatus (2n = 42) and Apeltes quadracus (2n = 46), to ascertain the types of chromosome rearrangements that differenti...

متن کاملHydrology controls recruitment of two invasive cyprinids: bigheaded carp reproduction in a navigable large river
In the Mississippi River Basin of North America, invasive bigheaded carp (silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities...
متن کاملRecurrent Cystic Hygroma with Normal Karyotype in Two Consecutive Pregnancies
We herein describe a woman with two consecutive pregnancies affected by fetal nuchal cystic hygroma (CH) with a normal karyotype. A 33-year-old woman (gravidity 2, parity 1) was referred to us because of fetal hydrops. No consanguinity or Rh isoimmunization was involved in her current or previous pregnancy. First-trimester ultrasonography revealed nuchal CH, and chorion villus sampling was perf...
