While comparative bacterial genomic studies commonly predict a set of genes indicative of common ancestry, experimental validation of the existence of this core genome requires extensive measurement and is typically not undertaken.
Specifically the following markers M92, M406 and J2a- DYS445 J2a- DYS445hosen as indicative of Neolithic ancestry.
The D-loop also contains two hypervariable regions, which are indicative of maternal ancestry [ 3].
In several cases, a common recombination site was observed in chromosomes belonging to two or more hybrids, indicative of common ancestry.
Previous studies on DNA replication of Archaea have already shown that the core replication machineries of the eukaryotes and Archaea possess fundamental similarities and have many homologous protein components [ 35], indicative of common ancestry.
To determine whether the Lp14 perA gene also contained a deletion, we sequenced a PCR product amplified from the perA-EF104 region and remarkably found an identical deleted perA as in E2368, indicative of shared ancestry of these two strains.
From the genomic point of view, the presence of several hundred genes having higher sequence similarity with Drosophila melanogaster and Caenorhabditis elegans than with vertebrates [ 14], as well as the small gene number, are indicative of species ancestry.
Polymorphisms indicative of African ancestry, including the rs2814778 SNP, were analyzed using the Sequenom MassARRAY platform and iPLEX Gold chemistry at the Children's Hospital of Oakland Research Institute (CHORI) Functional Genomics Core (Maglott et al, 2007; Wassel Fyr et al, 2007; Nalls et al, 2008).
Intriguingly some NRY haplogroups that are possibly (though further resolution would be required) indicative of European ancestry (P* xR1a), J and possibly F, G, and I) are found at very low frequencies amongst the Cross River samples and may have entered the Cross River gene pool as a consequence of male introgression of slave traders.
Despite the diversity of β-propellers, their blades frequently show sequence similarity indicative of a common ancestry and are thought to be a result of independent amplification of an ancient blade-sized fragment [ 22, 23].
