In contrast, the very limited number of taurine alleles of the Y-chromosome
reported for the north Ethiopian cattle population could be a result of recent crossbreeding or incomplete introgression of zebu patrilines .

The two Y-chromosome
regions, SRY and DYS14, were demonstrated to specifically indicate the sex of the embryo when assessed by melting curve analysis.
Geneticists point out that mitochondrial Eve and Y-chromosome
Adam are not synonyms for the biblical Adam and Eve for at least three reasons.
They found that a particular Y-chromosome
haplotype--referred to as the Cohen modal haplotype (CMH)--was present in the Lemba at a frequency of 8.8% (12/136).
High frequency of well-defined Y-chromosome
deletions in idiopathic Sertoli cell-only syndrome.
So do we in the church value all members of the church equally, or are we prepared to discriminate merely on the presence of a Y-chromosome
? The nation sees this discrimination as morally reprehensible and abusive towards women, as do the vast majority of the members of the church.
While males carry one X and one Y-chromosome
, females' two X-chromosomes could result in a potentially toxic double dose of genes-except for a unique evolutionary mechanism whereby one of the two X's is silenced in a process known as "X-inactivation."
The second study considered the genetic histories of three groups from the Northwest Territories--the Inuvialuit, the Gwich'in and the Tlicho--building up the most complete Y-chromosome
data set of these communities yet created.
"The acrocentric nature of the Y-chromosome
establishes that the Vechur cattle belong to the species of the Zebu cattle (bus indicus) as different from the European cattle (bus taurus) which has metacentric y-chromosome
."--Source: B.C.Venkata Krishnan, Founder and Moderator, Ahimsa Foundation, Headquarters, Chennai, Tamilnadu, India.
While the specific pathway for affecting CAD is not yet understood, the Y-chromosome
finding may explain why certain men without traditional cardiovascular risk factors such as smoking or high cholesterol still develop heart disease.
Genomic DNA was extracted from blood samples, then mitochondrial DNA (mtDNA) control region sequences, a Y-chromosome
haplotype (male only), and genotypes based on twelve autosomal microsatellite loci were generated as in Wheeldon et al.
