To ne može bit točno jer postoje križanci tigra i lava. Dakle, genetski moraju biti puno bliže nego mi sa čimpanzama koje su na 96%, a ne 99%. Za referencu, sa žabama dijelimo 90% genoma, a bananama nekih 60 ili 70%.

The scientific name of a lion is Panthera leo and the scientific name of a tiger is Panthera tigris. Because they share the first part of their scientific name (meaning that they belong to the same genus, which is one rank above species. This means that they share a very close ancestor, perhaps only one ancestor. Because of this, they could (theoretically) mate, but this will always result in sterile hybrids such as the liger.
Humans and chimpanzees however, while belonging to the same family (Hominidae) are in two separate genera: Humans are Homo sapiens and Chimps are Pan troglodyte. Because they are from two separate genera, offspring is not possible because of how much we have deviated from each other.
Lions and tigers’ genetic relationship is more akin to that between humans and Neanderthals (replacing chimpanzees with Neanderthals here because they’re more closely related to us than chimpanzees are. Chimpanzees can’t breed with us, unlike Neanderthals).
Like humans and Neanderthals, lions and tigers belong to the same genus. Whereas humans and Neanderthals belong to the Homo genus, lions and tigers belong to the Panthera (“big cat”) genus. Humans and Neanderthals could reproduce together. Likewise, lions and tigers are genetically close enough to produce hybrid offspring when they mate.
Sa drgim rijecima ti procenti isto ne daju cijelu sliku. Iako smo dosta slicni cimpanzama u procentima to ne znaci automatski da bi mogli imati offspring kao tigar i lav. Vise stvari tu igra ulogu. Ali interesantno pitanje.
