Steps in a reproductive process used to produce a sheep with certain traits are listed below. Step 1 - The nucleus was removed from an unfertilized egg taken from sheep A. 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?

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.

Step 2 : The nucleus of a body cell which is taken from sheep B was then

inserted into this unfertilized egg which is taken from sheep A. Now the egg contain nucleus of sheep B.

Step 3 : The resulting cell containing nucleus of sheep B was then implanted into the uterus of

sheep C.

Step 4 : finally Sheep C gave birth to a sheep named sheep D.

Sheep B would be most genetically similar to sheep D, because the nucleus was taken from sheep B, and the sheep D is the new born which is formed from the nucleus of sheep B.
