Do babies from egg donation share genes with the birth mother?

Egg donor babies do not share the genetic load of the birth mother, but that of the egg donor, who is in fact the biological mother.

Nevertheless, recent studies have shown that recipients of donor eggs still pass some traits of their DNA through a phenomenon called epigenetics, a branch of Biology that studies the influence of a person’s lifestyle on who he or she is, regardless of the gene expression.

So, factors such as the mother’s diet during pregnancy could affect the development of the baby-to-be’s gene expression.
