Cytogenetic Findings in Mentally Retarded Iranian Patients
We conducted a cytogenetic study on 865 individuals with idiopathic mental retardation (MR) who were admitted to the Cytogenetics Department of the Iran Blood Transfusion Organisation (IBTO) Research Centre, Tehran, Iran; these were performed on blood ...

Insect Sex Determination Manipulated by Their Endosymbionts: Incidences, Mechanisms and Implications
The sex-determining systems of arthropods are surprisingly diverse. Some species have male or female heterogametic sex chromosomes while other species do not have sex chromosomes.

Prenatal Diagnosis and Pregnancy Outcome Analysis of High-risk Fetuses Suggested by Noninvasive Prenatal Screening [PDF]
Background Noninvasive prenatal screening is more effective in screening for fetal aneuploidy than does traditional serological screening. We attempted to analyze the real-world data about the positive predictive value (PPV) for chromosome aneuploidy ...

Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.

Classical and molecular cytogenetic studies in some cattle breeds
Numerical autosome aberrations have a few importance in the animal breeding since the carriers show generally abnormal body conformation. For this reason, these abnormalities are systematically eliminated from the animal population by the breeders during

Independent stratum formation on the avian sex chromosomes reveals inter-chromosomal gene conversion and predominance of purifying selection on the w chromosome [PDF]
We used a comparative approach spanning three species and 90 million years to study the evolutionary history of the avian sex chromosomes. Using whole transcriptomes, we assembled the largest cross-species dataset of W-linked coding content to date.

Early events in the evolution of the Silene latifolia Y chromosome: Male specialization and recombination arrest [PDF]
Understanding the origin and evolution of sex chromosomes requires studying recently evolved X-Y chromosome systems such as those in some flowering plants.
