Presentation transcript:

Which sheep is the source of the nucleus in the fused cell? Which sheep provided an egg cell? Why was the nucleus removed from the egg cell? Which animal in the above diagram is a clone? Which two animals are genetically identical? Provide at least 2 example of how clones are produced in nature (not a lab)/ Does the lamb receive any genetic material from sheep C? If you only had one sheep, instead of three (A,B, and C) above, would it still be possible to make a clone? If so, which one would it have to be? Can a male be used in the cloning process? If so, what roles could he be used for (A, B and/or C?)

Which sheep is the source of the nucleus in the fused cell? -Sheep A Which sheep provided an egg cell? -B Why was the nucleus removed from the egg cell? -It was missing half of the genetic information that was needed that is necessary to make a clone. (Wanted A’s DNA). Which animal in the above diagram is a clone? -Lamb

Which two animals are genetically identical? -Lamb and Sheep A Provide at least 2 example of how clones are produced in nature (not a lab) -Identical twins, bacteria (binary fission), asexual reproduction (mitosis) Does the lamb receive any genetic material from sheep C? -No, it just lets the cell grow. (Acts as a surrogate).

8. If you only had one sheep, instead of three (A,B, and C) above, would it still be possible to make a clone? If so, which one would it have to be? Sheep B since they are female. Can donate somatic cell, egg cell and be a surrogate. 9. Can a male be used in the cloning process? If so, what roles could he be used for (A, B and/or C?) Yes, they can donate the cell for the nucleus.
