The old man.....I thought the same. I was interested and did some researching. (Had lots of time on an airplane with nothing better to do LOL)
Seems the pure Eurasian and Asian (36) and domestic (38) can produce hybrid (37). And hybrid (37) bred to a Hybrid (37) can produce viable offspring with (36) (37) and (38) chromosome animals in the same litter. Pretty interesting stuff, I never knew possible.
I used to raise a bunch of wild caught hogs to mess with and supply a trophy club. Seemed like genetics played the biggest role in the boars teeth (not suprising). Even with high protein feed....The ones with the good genetics grew the big teeth, The ones without didnt. Barring them helped them keep there teeth intact longer(not fighting, marking) but didnt help the genes not grow them.
Thats interesting never knew that. I agree with genetics in general for tooth size. there were areas id hunt where most everything had big teeth (like Corsicana) even small hogs, and Greenville/Farmersville caught a lot of huge hogs most small tusks, and Terrell 50/50%. IDK really and of course exceptions in every spot but generally went like that for years...
