Both the mother and father contribute DNA to the overall genotype of the baby. However only the mother's DNA gets contributed to the baby's mitochondrial DNA. Mitochondrial DNA enables geneticists to trace a lineage far back in time versus chromosomal DNA at just 3 or so generations.
If you're interested, read up on the female inheritance portion on the link.

Wow! The user Danielle R on here is very smart and gave the best possible and correct answer without having to explain too much. So both the mother and the father contribute half or 50% of their DNA to their baby along with most traits.

The baby gets half of it's DNA from both parents and then grows as a separate being in the womb although getting nutrient only from mother. During development will produce it's own blood type.

when it comes to the DNA of a baby the mother takes half of her DNA and mashes it together with the father s giving the baby a totally unique DNA that no one else has

both of them do. 23 chromosomes come from the mother and 23 chromosomes come from the father. when the sperm and egg fuse together, the two 23 chromosomes combine together and the childs first cell is formed. the process is called fertilization of the egg, you can wikipedia or google it for a better answer.
by the way, most of the mitochonidrial DNA is in the human genome so it doesnt really matter. mitochondria only have like 5-15% of their genomes now. the thing you should be focused on is that 23 come from mom and 23 come from dad.

Both. Half comes from the mother and half comes from the father.

they BOTH do!!!! a baby is 50-50 mum and dad. i know that a child may look more like one than the other, but there is a lot more to DNA than what you look like. tehre are plenty of other things to be determined by DNA than looks and babies are half mum, half dad

Both.
The sperm has only half of the information and the egg has half. They must combine to create a whole DNA strand.

Both...that is how the offspring obtain 23 pairs of chromosomes...one from the father and one from the mother.
