The karyotype of the Muscovy duck originating from Cairina moschata was characterised on the basis of R and C bands. Chromosomal preparations obtained from an in vitro blood lymphocyte culture were RBG- and CBG-stained. The structures of nine and fourteen pairs of chromosomes were examined based on R bands and C bands, respectively. Ideograms of banded patterns of the analysed chromosomes were drawn. The sizes of individual constitutive heterochromatin blocks wereas measured. The morphology of… Expand
Constitutive Heterochromatin Pattern of Five Domestic Duck Breeds, (Aves: Anatidae) in Egypt
Constitutive heterochromatin patterns of five domestic duck breeds three of Anas platyrhynchos (Dumyati, Khample and Pekin) and two of Cairina moschata (Muscovy and Sudani) occurring in Egypt haveExpand
Constitutive heterochromatin in chromosomes of duck hybrids and goose hybrids
TLDR
Analysis of karyotypes of F1 hybrids resulting from intergeneric hybridization of ducks and geese and interspecific crosses of geese revealed nearly twice as much constitutive heterochromatin in the chromosomes of the hybrid as when chromosomes from the goose hybrid were compared with those of the geese.

Genetic Resource of Muscovy Duck (Cairina moschata): Profile and Potential Production as Meat Producer
Muscovy duck is a type of waterfowl that has a relatively better growth and percentage compared to ducks. Duck meat has high-quality because of its low fat and savory flavor. Muscovy duck isExpand

TLDR
Compared with 12 wk, subcutaneous fat tissue at 35 wk upregulated several genes related to cholesterol biosynthesis and fatty acid biosynthesis, while it downregulated fatty acid beta-oxidation related genes, including ACOX1 and ACSL1, consistent with the slower metabolism of aging duck. Expand

International System for Standardized Avian Karyotypes (ISSAK): standardized banded karyotypes of the domestic fowl (Gallus domesticus)
TLDR
An international committee met to develop a karyotype for the eight largest chromosomes and the Z and W chromosomes of the domestic fowl (Gallus domesticus) and this map is presented. Expand
Synaptonemal complexes and the chromosome complement of domestic fowl, Gallus domesticus.
TLDR
Synaptonemal complexes (SC's) were compared to their chromosomes by transmission electron microscopy of whole-mount spreads from 42 male chickens and revealed a graded series of SC lengths with a 30-fold difference between the longest and the shortest SC. Expand
Chromosomes in Birds
TLDR
The analyses of chd genes present on Z and W sexchromosomes of birds show that evolution in them is male driven, thus supporting a neutral model of molecular evolution. Expand
Chromosomes in birds (Aves): evolutionary implications of macro‐and microchromosome numbers and lengths
TLDR
It is proposed that the smallest macrochromosomes (nos. 7–10) have been created by Robertsonian translocations of larger microchromosome and that translocation of micro Chromosomes to macrochromOSomes shifts the centromeric position from telocentric to submetacentric or metacentric. Expand
New Giemsa method for the differential staining of sister chromatids
TLDR
If human lymphocytes1 or Chinese hamster2 cells are treated with the base analogue 5-bromodeoxyuridine in the latter part of the S period, Giemsa stained chromosomes exhibit a pattern of condensed and extended segments along their length, allowing the identification of the two chromatids, and the observation of sister chromatid exchanges (SCEs) without recourse to autoradiography.

Molecular Cytogenetic Definition of the Chicken Genome: The First Complete Avian Karyotype
TLDR
The molecular cytogenetic characterization of each chicken chromosome is described using chromosome painting and mapping of individual clones by FISH and it is proposed, on the basis of size, that the NOR chromosome is approximately the size of chromosome 22. Expand

Comparative gene mapping between the genomes of chicken, human, mouse and zebrafish is used to investigate the origin and evolution of avian microchromosomes and reveals evidence for four ancient syntenies conserved in fish, birds and mammals for over 400 million years. Expand
