I wondered about whether genealogy was about genes. But I think that lots of people want to record adoptive family, among other things.

As for types of biological parentage:

Gestational surrogacy, where a baby is borne by someone other than the people who provided sperm and egg. Pregnancy even affects the mother's DNA.
A third parent can provide mitochondrial DNA to avoid a rare disease.
You might consider someone who regularly breastfeeds a child as a biological relation. They certainly transmit protective antibodies. Science doesn't have a full understanding of everything that breastfeeding does. Milk kinship is an idea in some cultures and it may have biological kinship effects.
There may be more types of biological parentage in the future - science is active in this area.
