Question

70. With reference to ‘Three parent technique’, recently seen in the news, consider the following statements:
1. It involves fertilising both the mother’s egg and a donor egg with the father’s sperm.
2. It is legally approved in India.
Which of the above statement(s) is/are correct?

• A. Only 1
• B. Only 2
• C. Both 1 and 2
• D. None of the above

Answer 1

The correct option is A Only 1

Three parent techniques involve fertilising both the mother’s egg and a donor egg with the father’s sperm. Before the fertilised eggs start dividing into early-stage embryos, each nucleus is removed. The nucleus from the donor’s fertilised egg is discarded and replaced by that from the mother’s fertilised egg. The resulting egg – with nuclear DNA from the mother and mitochondrial DNA from a donor – was then fertilised with the father’s sperm. It is legally approved in the UK.
