    On a debate group i have joined they brought up the idea of cloning your pets, someone argued that cloning doesn't make the pet identical. I understand that there are environmental variables in play here and also X-inactivation in female mammals which will make the cloned animal not identical to the original animal. But lets imagine the original animal is male and we can ignore other environmental factors- if the animal is say white with black spots will the cloned animal have the black spots in the exact same position of the body. Of course the genes will code for that animal to have white fur with black spots but do the genes code exactly where those black spots should occur on the body?

    In reality, color pattern locations are not coded for in the DNA. The conditions to create the patterns are, such as spots, stripes or others, but the actual locations are driven by random processes.

    I agree with you. Most of the time cloning not acceptable to others. We never control people to easily accept truth.

    No; pigmentation has a significant degree of randomness to it. Environmental and epigenetic factors along with random mutations mean that clones aren't 100% identical to their progenitors.
