Hi!

Here’s my interpretation:

  1. This is correct because when animals are cloned directly through embryo transplants they will all contain the same set of genes, meaning they would be genetically identical.

  2. This is correct because genetic material from an unfertilised egg during adult cell cloning may contain different genetic material that will result in an organism that is not a perfect clone, so the genetic material is removed in order to ‘start from scratch’ and produce identical clones.

  3. This is correct because cloning will produce identical organisms, meaning genetic variations will decrease and result in a reduced gene pool (as opposed to non-cloning methods which tend to increase genetic diversity).

  4. This is incorrect because other organisms apart from mammals (e.g. insects) can also be cloned.

So the answer is E.
