What genes are inherited from mother only?

It’s Not Only About the Chromosomes The mitochondrial genes always pass from the mother to the child. Fathers get their mitochondrial genes from their mothers, and do not pass them to their children.

children are more likely to inherit intelligence from their mothers because intelligence genes are located on the X chromosomes (and mothers have two). Mothers do tend to have two X chromosomes, but they aren’t identical chromosomes, and of course, they got one of them from their fathers.
