Answer:

It will decrease in speed.

Explanation:

In our daily lives, it is more common to witness sound propagating in the air, but nothing prevents sound waves in liquids and solids. In fact, air is not a good medium for sound propagation. Despite causing the sound to travel at a relatively high speed of approximately 340 m / s, liquids allow the waves to propagate even faster.

Solids are also efficient propagation media, however, when sound waves pass through them, the speed of the sound wave is decreased.

Therefore the three genetic materials from different parents (mitochondria from donor mother, DNA from biological mother and DNA from biological father) would be present in the baby.
