What DNA Does a woman inherit from her father?

Sex Chromosomes (X Y)

Women inherited two copies of the X chromosome – one from each parent – while men inherited one X chromosome from their mother and one Y chromosome from their father. Since men and women have different sex chromosomes, there are some small differences in the ancestry information they receive.

Does the bloodline come from the father?

There are two (and only two) sources of DNA, however, that do not mix the mother’s and the father’s DNA. … Each son receives DNA for his Y chromosome from his father. This DNA is not mixed with that of the mother, and it is identical to that of the father, unless a mutation occurs.

Can a child be smarter than parents?
