Consider the following statements: 1. Genetic changes can be introduced in the cells that produce eggs or sperms of a prospective parent. 2. A person's genome can be edited before birth at the early embryonic stage. 3. Human induced pluripotent stem cells can be injected into the embryo of a pig. Which of the statements given above is/are correct?

1. Correct. Germline gene editing can be done in cells that give rise to eggs or sperms, so genetic changes can be introduced in a prospective parent’s reproductive cells.
2. Correct. Genome editing can be carried out at the early embryonic stage before birth; this is the basis of embryonic/germline editing.
3. Correct. Human induced pluripotent stem cells have been introduced into pig embryos in chimera research.

Hence, all three statements are correct.
