Understanding Sheep Breeds and Cloning
The breed of sheep known for having good maternal characteristics, being solid white, and having drooped ears is the Suffolk. Therefore, the correct choice is d) Suffolk. Now, regarding the famous cloned sheep Dolly, it is important to note that Dolly was not a Suffolk but rather a Finn-Dorset sheep. The nucleus used in the cloning process that resulted in Dolly was taken from a mature somatic cell of a Finn-Dorset sheep, making option b) the correct answer to the question about Dolly's breed. It is incorrect to associate Dolly's breed with either cytoplasmic or epigenetic inheritance in this context.
