Genesis 30:37 And Jacob took him rods of green poplar, and of the hazel and chesnut tree; and pilled white strakes in them, and made the white appear which was in the rods. 30:38 And he set the rods which he had pilled before the flocks in the gutters in the watering troughs when the flocks came to drink, that they should conceive when they came to drink. 30:39 And the flocks conceived before the rods, and brought forth cattle ringstraked, speckled, and spotted.
So according to the Bible all you got to do to get the traits you want is to show an organism the trait you want while it concieves and it's young will be born that way.
Sorry but that's been disproved like 300 years ago so I will believe in modern genetics over Bibical genetics. And there are hundreds of other scientific inacuracies in the bible
Just because Global Warming is Junk Science doesn't mean ALL modern science is false.
In reality, it was genetics that caused it because the spotted, streaked, and speckled animals had previously not been separated from the solid colored ones, so their genes would have all of those traits co-mingled in their DNA.
