Adottare un cane è una questione di geni. Uno studio condotto su oltre 35'000 coppie di gemelli indica che la disponibilità ad averne è scritta nel DNA, come pubblicato su Scientific Reports.
"Abbiamo visto che la genetica influisce in modo significativo sulla volontà di tenere un cane", ha dichiarato Tove Fall, coordinatore dello studio. Si tratta di un risultato che può avere implicazione nel comprendere il rapporto che l’uomo ha con questi animali. "Forse alcune persone hanno una propensione maggiore a prendersi cura di loro rispetto ad altre", ha continuato Fall.
Lo studio sui gemelli permette di distinguere le influenze ambientali da quelle genetiche sulla nostra biologia e sul nostro comportamento. È stato dimostrato che il tasso di concordanza sulla decisione di avere un cane è maggiore negli omozigoti, ovvero che possiedono lo stesso patrimonio genetico, rispetto a quelli eterozigoti, vale a dire che condividono solo il 50% del corredo.
