In the context of hereditary diseases, consider the following statements :
1. Passing on mitochondrial diseases from parent to child can be prevented by mitochondrial replacement therapy either before or after in vitro fertilization of egg.
2. A child inherits mitochondrial diseases entirely from mother and not from father.
Which of the statements given above is/are correct?

Correct Option: Both 1 and 2

Mitochondrial replacement therapy (MRT) is an advanced form of IVF used to prevent mitochondrial diseases from passing from mother to child by replacing faulty mitochondria with healthy donor mitochondria, either before or after egg fertilization. Furthermore, mitochondrial DNA is inherited exclusively maternally because sperm mitochondria are typically destroyed or excluded during fertilization. Therefore, both statements 1 and 2 are correct.
