Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]
In situ hybridization experiments were carried out with two clones, YACG 35 and 2.8, which had been selected from two genomic libraries strongly enriched for the human Y chromosome.

X chromosome inactivation during Drosophila spermatogenesis [PDF]
Genes with male- and testis-enriched expression are under-represented on the Drosophila melanogaster X chromosome. There is also an excess of retrotransposed genes, many of which are expressed in testis, that have “escaped” the X chromosome and moved to ...

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

The spectrum and prevalence of genetic pathology among the population of a certain region are determined by the founder effect and microevolution factors and, therefore, are not always comparable in different countries.

Chromosome 15 Imprinting Disorders: Genetic Laboratory Methodology and Approaches
Chromosome 15 imprinting disorders include Prader-Willi (PWS) and Angelman (AS) syndromes, which are caused by absent expression from the paternal and maternal alleles in the chromosome 15q11. 2–q13 region, respectively.

Disorders caused by chromosome abnormalities
Many human genetic disorders result from unbalanced chromosome abnormalities, in which there is a net gain or loss of genetic material. Such imbalances often disrupt large numbers of dosage-sensitive, developmentally important genes and result in specific and complex phenotypes.

Chromosomal aberrations as a cause of infertility: diagnosis and genetic counseling in Las Tunas
Background: infertility is a clinical problem with a significant social medical impact on the health of the couple. It is considered that 36 % of the genetic causes of infertility are caused by chromosomal aberrations.Objective: to describe the results ...

Chromosome transplantation as a novel approach for correcting complex genomic disorders
Genomic disorders resulting from large rearrangements of the genome remain an important unsolved issue in gene therapy. Chromosome transplantation, defined as the perfect replacement of an endogenous chromosome with a homologous one, has the potential of
