The tilt of the earth changing would affect the distance to the sun. This, the radiation from the sun, and resulting temperatures, would change as well.
Dolly was a female fin Dorset sheep,
Although it has been claimed that dolly had 3 mothers. one provided the egg, another the DNA, and a third carried the cloned embryo to term.
So therefore, dolly has the genes of different species of sheeps.
Hope this helped!
