Step 2 — The nucleus of a body cell taken from sheep B was then inserted into this unfertilized egg from sheep A. Step 3 — The resulting cell was then implanted into the uterus of sheep C. Step 4 — Sheep C gave birth to sheep D. Which sheep would be most genetically similar to sheep D?

Respuesta :

Answer:  

Sheep B

Explanation:

As given;  

Step 1:  The nucleus was removed from the egg which was unfertilized and,

which is taken from sheep A, means that the egg was from sheep A.
