Becoming a Mother Through Egg Donation: Does the Child Receive DNA and RNA from the Mother?

If you become a mother through egg donation, the child will not receive DNA from you, but there will be a significant epigenetic interaction.

DNA (Genetic Material)

• The child's DNA comes from the egg donor and sperm provider
• You cannot change the child's genetic code during pregnancy
• The child carries the genetic characteristics of the donor and your partner

RNA and Epigenetic Effect However, there is a very important point here:

Your interaction during pregnancy:

• MicroRNA and other molecules pass to the baby through the placenta
• These molecules can affect the baby's gene expression (which genes turn on or off)
• Your nutrition, stress levels, and environmental factors influence the baby's epigenetic programming
• This effect can play a role in the baby's development and even later in life

This means:

• DNA: From the donor and sperm provider
• Epigenetic effect: From you (throughout pregnancy)
• RNA transfer: Yes, RNA and other regulatory molecules pass from you to the baby through the placenta

In other words, even though you don't transfer DNA genetically, you significantly influence the baby's gene expression and development during pregnancy. This is a scientific fact showing that the biological maternal bond is not just about DNA.
