The First Cloned Cat, Called Carbon Copy, Was a Calico

The first cloned cat, called Carbon Copy, was a calico, but she looked significantly different from her female parent. Why was this the case with this clone?

A) The cloning was done poorly and it was likely that some contaminating cat DNA became part of Carbon Copy's genome.
B) Fur colour genes in cats is determined by differential acetylation patterns.
C) Cloned animals have been found to have a higher frequency of transposon activation.
D) X chromosome inactivation in the embryo is random and produces different patterns.
