Cytogenetic abnormalities and Y-chromosome
microdeletions in infertile Syrian males.
The same reasoning applies to a common Y-chromosome
Increasing the resolution of Y-chromosome
analysis that included 75 binary markers and 22 STR markers, Hammer et al.
Looking at the DNA in the Y-chromosome
and the mitochondria, we are able to have a fair idea about a person's male and female lines, and possibly where they might have come from.
Screening for Y-Chromosome
Microdeletions in a Population of Infertile Males in the Gaza Strip.
Another consideration is that, if Y-chromosome
testing is increasingly used, (186) males may be disproportionately represented in DNA databases and partial match searches.
SW: All existing mtDNA and Y-chromosome
haplogroups are descended from a most recent common female and most recent common male ancestor.
1) The test detects Y-chromosome
DNA, which indicates the presence of sperm, up to two weeks after unprotected intercourse.
Both sex chromosomes were submetacentric with smaller Y-chromosome
compared to X-chromosome.
This document provides a framework for the laboratory to develop Y-chromosome
short tandem repeat (Y-STR) interpretation guidelines.
Martinez Cruzado and his team have also completed preliminary but unpublished research on the Y-chromosome
of Puerto Rican islanders; however, this research has not received the kind of attention and hyped-up publicity that the mtDNA research has received.
phylogeography most likely reflects the effects of drift.
