Suppose that a nucleus from a Finn-Dorset sheep named Ethel (the nuclear donor) is combined with an enucleated egg from a Scottish Blackface sheep named Maria (the cytoplasmic donor), and is put into a surrogate Scottish Blackface ewe named Brenda, resulting in the birth of a female lamb named Dolly. What can we say about Dolly?

a.
Her DNA is a combination of Ethel's, Maria's, and Brenda's DNA.

b.
She is a genetic clone of Ethel.

c.
She is a genetic clone of Brenda.

d.
She is a genetic clone of Maria.

e.
Her DNA is a combination of both Ethel's and Maria's DNA.
