It is important to remember in all the fireside Jacob tales that conning, cheating and getting even shows up. There are examples among the wives, between Laban and Jacob, between Jacob and his father and brothers, even between Jacob and God.
In Genesis 32:22-32 God tries to wrestle with Jacob and beat him but fails. The God character finally pushes a nerve on Jacobs hip to wrench Jacobs hip but Jacob still doesn't give up and so God has to cry Uncle.
But all that is irrelevant to the topic and the topic clearly claims that making goats face branches and bark while breeding will determine whether they are striped, spotted or streaked.
That's utter nonsense but great material for a story teller, a fireside fable and written just like the old Saturday Serials. The continuing saga of Jacob meant that the story teller got fed and sheltered for the night and he'd spin out the next chapter for his meal then next night.
Anyone so limited that they can only spell a word one way is severely handicapped!
