I am not well versed in this subject, perhaps obviously, however I am thinking my daughter would have only my x from my mother and her mothers x leaving no connection?

Yes. The odds are very high (although not exactly 100%) that she will get some of your father's chromosomes. (Chromosomes are where the main DNA is located.)
You are correct that your X chromosome came from your mother, which is what you passed to your daughter.
But that is only 1 out of the 23 chromosomes that you passed on to your daughter. (Remember that humans have 46 chromosomes, so *exactly* 23 came from you.)
Of the remaining 22 chromosomes, they could all come from your mother, OR all from your father ... but the odds of that happening are *extremely* small. What's most likely is something like 10 from one parent, and 12 from the other. Or maybe 13 from one parent, and 9 from the other. Basically, the odds are that *roughly* 1/2 of the chromosomes you gave her, came from your father, the other 1/2 from your mother ... so roughly 1/4 of her chromosomes came from your father (the other 1/4 each from each of the other three grand parents).
If you have a son, you are guaranteed to pass on at least one of your father's chromosomes ... your Y-chromosome. (Basically, every male relative you know that has the same last name, has the same Y-chromosome.) But the other 22 could come from either of your parents.
Incidentally, this often confuses people (you are not alone). It seems odd that your daughter gets *exactly* 1/2 of her chromosomes from each of her parents ... but *not exactly* 1/4 from each of her grandparents. (It can be anywhere from 0 to 1/2 from each grandparent as long as all four add up to 1.) But if you do the numbers, it makes sense ... it is not possible to divide 46 evenly by 4 ... so it's not possible that each grandparent contributes *exactly* 1/4 of a child's chromosomes.
In fact, this is why some children can look more like one of their grandparents than the other three. In fact, some kids can look more like one of their grandparents than either of their own parents! E.g. your daughter could express a lot of genes from one of your parents that are not expressed in you (because they are recessive, and cancelled by your other parent's genes, which she did not inherit).
---
Incidentally, at the risk of overanswering your question (as if I haven't already), there is also the issue of mitochondrial DNA. This is DNA outside the chromosomes. However, all children inherit this directly from the mother ... your daughter didn't get any mitochondrial DNA from you, and thus none from your parents. However, while interesting for tracing maternal lineage, mitochondrial DNA is not significant as far as visible traits.

Yes, they would definitely share DNA in common. Genes are stored inside chromosomes. A child gets a copy of 23 chromosomes from both of their parents, giving them 46 total chromosomes. So most likely, your daughter has some chromosomes that are the same as your fathers.

Yes, statistically, your daughter would share 1/4th your father's DNA.
You have 1/2 of the DNA from your dad.
Your daughter has 1/2 of your DNA.
Statistically speaking, 1/2 the DNA that you share with your daughter came from your dad.
so...1/2 of 1/2 is 1/4th...the amount of DNA that your dad shares with your daughter.

You are a male named bubbles?
Your Father and Daughter do share the same dna, except only certain chromos.

They would share some markers. We all get 1/2 of our DNA makeup for each parent...so in laymans terms, she would end up with 1/4 of each grandparents on bothside of her family. Since you got 1/2 from each of your parents.

I don't get it, if she's your daughter then yes your father and her share some common dna! His blood flows through her bloodstream!!!

yes. they would not share sex-linked traits, although you and your daughter would, but due to crossing over of genes in homologous pairs of chromosomes, some of your genes (50% of which come from your father) will go to your daughter. 25% of your daughter's DNA will be from him (theoretically), although much less than 25% may display itself.

Your daughter got 1/4 of her non-sex genes from your father.
She got one of her Xs from her mother (cannot tell whether it was from Mum's mother or Mum's father.
Your daughter got her other X from your mother (your daughter's paternal grandmother) - via YOU! (emphasis, not shouting)

Yes there will be some same characteristics showing the same blood line

she would
because she would get DNA from you, which you got from YOUR father
however, since she's female, she wouldnt get as much as DNA from YOUR father, as from your wife's father
