Just keep watching it and listening real good., Maybe get a dictionary and look up the words you might not understand. You will eventually get it!View attachment 12099
F1 in his example is a Hereford/angus female crossed with a charolais bull.
So angus/herford /charolias = 3 different breeds . 1+1+1 = 3 way cross
Very similar to a red angus dam crossed to a charolias cross bull = a 3 way cross
