what is the purpose and use for tracing your father's ancestry if daughter's don't carry the y chromosome wouldn't that mean that the daughter's are not related to the father on the ancestry tree and if so explain to me if daughther's are how is that possible when we don't carry the y chromosome?

Most of your DNA is autosomal. You get that 50-50 from both parents. It is the only DNA that can prove paternity of a female.
Check out SMGF. They plan to start using autosomal for genealogy purposes. That is the Sorenson Molecular Genealogy Foundation.

>>the daughter's are not related to the father
Men have a Y and an X chromosome. Their contribution determines the sex of the baby. When they give an X they have a daughter. When they give a Y they have a son.

A double XX is a girl and a XY is a boy. This is not the
determining factor in tracing ones ancestral heritage.
The girl(daughter) carries half of the genetic structure of
the father.If you omit all the females from your heritage
you do not exist.

You have 22 chromosome pairs. 21 of them come 50-50 from mother and father. The last pair - the sex chromosomes. are XX for females and XY for males. Even in females you get one of the X's from the father.
