The Origin of a New Sex Chromosome by Introgression between Two Stickleback Fishes. [PDF]

open access: yes, 2019
Introgression is increasingly recognized as a source of genetic diversity that fuels adaptation. Its role in the evolution of sex chromosomes, however, is not well known. Here, we confirm the hypothesis that the Y chromosome in the ninespine stickleback,

Haplotype analysis for Irish ancestry

open access: yesForensic Sciences Research, 2020
Forensic haplotype analysis of the male Y chromosome is currently used to establish the number of male donors in sexual assaults, the number of male bleeders in blood pattern analysis, and for ancestry correlation to genetic founder populations in ...

Multiplex-Polymerase Chain Reaction for Detecting Microdeletions in The Azoospermia Factor Region of Y Chromosome in Iranian Couples with Non-Obstructive Infertility and Recurrent Pregnancy Loss [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2018
Background Approximately 15% of couples are infertile with the male factor explaining approximately 50% of the cases. One of the main genetic factors playing a role in male infertility is Y chromosomal microdeletions within the proximal long arm of the Y

Sex chromosome positions in human interphase nuclei as studied by in situ hybridization with chromosome specific DNA probes [PDF]

open access: yes, 1984
Two cloned repetitive DNA probes, pXBR and CY1, which bind preferentially to specific regions of the human X and Y chromosome, respectively, were used to study the distribution of the sex chromosomes in human lymphocyte nuclei by in situ hybridization ...

Detection of Partial AZFc Microdeletions in Azoospermic Infertile Men Is Not Informative of MicroTESE Outcome [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2019
Background Microdeletions of the Yq chromosome are among the most frequent genetic etiological factor of male infertility which spans the azoospermia factor regions (AZFa, AZFb and AZFc).

Characteristics of spermatogenesis in infertile men with the AZFc region deletions

open access: yesАндрология и генитальная хирургия, 2014
Spermatogenetic defects were analyzed in the cohort of 218 russian infertile men with various AZFc region deletions of the Y chromosome. Clear differences were found in both the percentage of pathozoospermia forms and sperm concentration between ...

Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]

open access: yes, 1984
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.

Sexual dimorphism in cancer

open access: yesУспехи молекулярной онкологии, 2023
The incidence and mortality of malignant neoplasms of non-reproductive organs both carcinomas and sarcomas in men is one and a half times higher than in women.

Natural selection reduced diversity on human Y chromosomes [PDF]

open access: yes, 2013
The human Y chromosome exhibits surprisingly low levels of genetic diversity. This could result from neutral processes if the effective population size of males is reduced relative to females due to a higher variance in the number of offspring from males

Genetics of the human Y chromosome and its association with male infertility

open access: yesReproductive Biology and Endocrinology, 2018
The human Y chromosome harbors genes that are responsible for testis development and also for initiation and maintenance of spermatogenesis in adulthood.
