Most geneticists accept that both are pretty important.

Do you mean Mitochondrial DNA? This isn't found in the blood, but within
the Mitochondria inside cells. Mitochondria are though to be descended
from bacteria that were taken up by primitive cells and became involved
in a symbiotic relationship. They reproduce independantly, and have a
remnant genome of their own. Since the sperm doesn't carry any normal
mitochondria, we only inherit them from our mothers. However the amount
of mtDNA compared to chromosomal DNA is tiny, and it's not involved in
controlling metabolic processes except within the mitochondria

Y-chromosomes are pretty small compared to X chromosomes, so a man
inherits slightly more of his mothers genes than his fathers. Probably
about a percent.

I'd suggest that if the child is being reared within the culture
of one of the parents, use that culture's modifiers, otherwise don't use
any modifiers at all.
