38. The first cloned cat, called Carbon Copy, was a calico, but she looked significantly different from her female parent. Why?
(A) The environment, as well as genetics, affects phenotypic variation.
(B) Fur color genes in cats are influenced by differential acetylation patterns.
(C) X inactivation in the embryo is random and produces different patterns.
(D) Cloned animals have been found to have a higher frequency of transposon activation.
(E) The telomeres of the parent's chromosomes were shorter than those of an embryo.
