What do daughters inherit from their fathers?
Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother. When your daughter inevitably ends up with his X chromosome, does that mean she’ll inherit all of his X-linked genes and traits? Genes, yes.
Do babies miss their dad?
