Hybrid zones can form from secondary contact. A hybrid zone exists where the ranges of two interbreeding species or diverged intraspecific lineages meet and cross-fertilize. . Hybrid zones can form in situ due to the evolution of a new lineage [1] [page needed] but generally they result from secondary contact of the parental forms after a period of geographic isolation, which allowed their ...
A hybrid zone may appear during secondary contact, meaning there would be an area where the two populations cohabitate and produce hybrids, often arranged in a cline. The width of the zone may vary from tens of meters to several hundred kilometers. A hybrid zone may be stable, or it may not.
Hybrizyme is a term coined to indicate novel or normally rare gene variants (or alleles) that are associated with hybrid zones, geographic areas where two related taxa (e.g. species or subspecies) meet, mate, and produce hybrid offspring. [1] The hybrizyme phenomenon is widespread and these alleles occur commonly, if not in all hybrid zones. [2]
It can occur across hybrid zones due to chance, selection or hybrid zone movement. [8] There is evidence that introgression is a ubiquitous phenomenon in plants and animals, [9] [10] including humans, [11] in which it may have introduced the microcephalin D allele. [12]
A tension zone is a transitional zone between two distinctive zones, the zones may be influenced by climatic factors, [1] [2] and geological variation. [ 3 ] creating a floristic tension zone. [ 4 ] A marine tension zone may be affected by variables such as depth, climate or salinity. [ 5 ]
The renovation of the Fadil Vokrri Stadium, located in Pristina, Kosovo, took place between 2016 and 2018. The stadium, which is the home ground for the Kosovo national football team and FC Prishtina, underwent significant upgrades to meet UEFA and FIFA standards, allowing it to host international matches.

Those of Albanian descent may choose to self-identify as Albanian, adopt hybrid identities or opt to not identify with their Albanian ancestry. [6] Many contemporary Albanians who belong to the diaspora opt to declare their ethnicity as their nationality, as seen in census underreporting of ethnic Albanians primarily in North America, South ...
