Surnames and the Y Chromosome [PDF]

open access: yesThe American Journal of Human Genetics, 2000
A randomly ascertained sample of males with the surname "Sykes" was typed with four Y-chromosome microsatellites. Almost half the sample shared the same Y-chromosome haplotype, which has not been observed in control samples either from the same geographic region or from the United Kingdom as a whole.

Association of X Chromosome Aberrations with Male Infertility

open access: yesActa Medica Bulgarica, 2021
Male infertility is caused by spermatogenetic failure, clinically noted as oligoor azoospermia. Approximately 20% of infertile patients carry a genetic defect.

The degeneration of Y chromosomes [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Y chromosomes are genetically degenerate, having lost most of the active genes that were present in their ancestors. The causes of this degeneration have attracted much attention from evolutionary theorists. Four major theories are reviewed here: Muller's ratchet, background selection, the Hill–Robertson effect with weak selection, and the ‘hitchhiking’

Assessment of Correlation between Androgen Receptor CAG Repeat Length and Infertility in Infertile Men Living in Khuzestan, Iran [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2015
Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (N- TAD).

Lack of Association Between Partial Y chromosome AZFc-gr/gr Deletions and Male Infertility

open access: yesBioMed Target Journal, 2023
A microdeletion in the azoospermia factor (AZF) region of the human Y chromosome long arm is the second most common genetic factor causing male infertility and spermatogenetic failure. The current study aimed to evaluate the occurrence of AZFc-partial gr/

The inexorable spread of a newly arisen neo-Y chromosome [PDF]

open access: yes, 2008
This work was financially supported by a Natural Environment Research Council grant to RAN. (NER-B-S-2003-00859) and a studentship from Queen Mary University of London to PV.A newly arisen Y-chromosome can become established in one part of a species ...

Is the Y chromosome disappearing?—Both sides of the argument [PDF]

open access: yes, 2011
On August 31, 2011 at the 18th International Chromosome Conference in Manchester, Jenny Graves took on Jenn Hughes to debate the demise (or otherwise) of the mammalian Y chromosome.

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
