When a baby is concived does the babys blood come from the mother from the father or both mother and father?

Question

Does the blood in your veins come from your mother your father or mom and dad?

Answer 1

The baby makes its own blood. It comes neither from the father or the mother. While it is in the womb, its own blood circulates through the cord and receives nutrients from the mother but the baby's blood and the mother's are separate and never normally mix.

Since the baby receives genes from both the mother and the father, the type of blood is influenced by that.

Answer 2

Hey! It depends on the baby...the baby can either have the mothers blood or the fathers..it is very important that you make sure you don't have an rh factor. What an rh factor is, is when you have a blood type..(ex. a- or b-) and your partner has a positive type or a univeral O type...this can interfere with the baby becuase if the baby has the positive and you are negative or vise versa, then your body will attack the baby thinking its foreign...so make sure you take care of that...also, good luck if you are expecting!

Answer 3

Babies blood is seperate actually from the mother's even in the womb.

Now, if you are asking about blood TYPE, it comes from both. Remember you get half of your chromosomes from your mother and half of your chromosome from your father.
Each chromosome has a homologous pair (remember meiosis?), and each gamete has half of the homologous pair.
Gamete from Mom provides half the genetic structure (eg type A), and one allele of the pair that codes for blood type, and Dad provides the second (eg type O). So it is a combination of both parents that provides the final genotype of the blood (AO). Each attribute has two genes coding for it in your body- one half from mom, one half from dad.

Hope this helps.
