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

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

You don't have to show the same blood type necessarily. Blood type is inherited like most other traits, you get one allele from mom and one allele from dad. except in the case of bllod there are three alleles for blood: A, B and O. A and B are codominant and O is recessive (which means in order to show O type you must have two O alleles). So if your dad is O (OO), and your mom is AA or AO, you could be AO or OO. If your dad is OO and your mom is BB or BO, then you could be BO,or OO. If your mom is AB and your dad is OO, then you could be AO or BO. \nAs you can see there are quite a few combinations, so this explains why you may show a different type from your dad.\n Rhesus factor (the + or -) is a different heritable trait and much simpler. You are either positive or negative. Hope this helps.\n\nFor further reading check out \nhttp://www.purchon.com/biology/abo.htm

Yes it is... My husband and I are both A+ and we have two healthy boys.  There might be a problem if one of the parents have got a negative RH factor, but if the problem is known then the mother is given a shot at the appropriate time and then it is not a risk anymore.

the female has 2 X chromasomes;\nthe male has 1 X and 1 Y chromasome; interestingly enough, it's the male who decides what gender a baby is going to be because either one X chromasome from the mother  joins with his one Y chromasome or his one X chromasome. It's kinda cool. ; )

You can rule out certain blood types, but you can't know the exact one for sure.  For example, you can be sure the father is not either blood type O or B, but he could be A or AB.  The rh factor isn't as easy to figure out.

no, the only time that blood type will be a concern is when the mother is Rh negative, and the father, Rh positive. The baby will be Rh positive like the father, because positive is dominant.\nThe problem with this is that if the baby's Rh positive blood mixes with the mother's Rh negative blood, the mother's blood will attack the baby's blood.\nThis looks bad, but doctors give Rh negative mothers shots before labor (and in any other situation where the blood might mix) to keep the mother and baby's blood from mixing.\nthat is the only genetic disadvantage that blood type can present.\nare congratulations in order?\nif so, CONGRATULATIONS!!!

No. A baby gets his DNA from mom and dad. Dad contributes 1/2 mom contributes 1/2. (Yes, this a simplified answer.)\n\nDNA testing can prove paternity because it looks for genetic markers that come from the dad.

This is called Chimera. After the mythological beast which had body parts of different sets of animals.\nA Chimera will usually have their blood and tissue of one DNA, while their reproductive organs and some inner organs will be of another. This is fairly random as to the "where" and "what," and it usually comes up as a concern in DNA testing when a mother is seemingly not the parent of her child. Or in crime cases where they cannot identify the rapist based on semen.\nThis condition occurs when two twins are begining to form within the womb, and for whatever reason one twin dies--and the other cell takes on the DNA--as a "clean up" if you will. The result is that the one cell finds no reason not to use the perfectly good DNA, and incorporates both wherever it sees fit.

if they were both active in the childs life and love the kid then that kid gets 2 moms and 2 dads without the drama at family get togethers. what's the problem? one could say my parents only got together to produce a child and they're both str8. but they didn't stay together so i didn't get the benefit of dual involvement. babies are made from sex not love. well rounded kids are made from love and not necessarily the love between 2 people but the love of that baby by those people.

The child can have all possible blood types. \n\nA + \nB + \nAB + \nO + \n\nIt would be extremely rare, but the children can also end up with - blood if the parents both have the recessive gene for the Rh factor.

Hemoglobin electrophoresis is the best method, but it requires fetal blood. If you and your baby's father are both B-Thal minor, then there is a problem. Otherwise, the Dr will probably choose to do the test at delivery.

The children would have bloodtype A or bloodtype B.\n\nThe "O" which they get from one parent is merely an absence of the information necessary to have specific antibodies against other bloodtypes.

I'm not certain of the context, but, taken literally, the logic follows... \n\n...as the child develops into the man, the child, or boy, in a sense, gives "birth" or gives way to the man, and thus is the origin or "father" or the man.

from parents XXh and XY the offspring would be:\n\nXX (a noncarrying female), XY (a normal male), XXh (a carrier female), and XhY (a hemophiliac male)

The answer is E. For a child to be AB, neither parent can be O, but can be any other blood type.  Keep in mind that each blood type has 2 alleles. The genotype for a B parent can be BB or BO, for A parent AA or AO, or the parent can also be AB. Different combinations of these can create an AB child, but if you have an O parent, that parent is always OO (because O is recessive if you want to look at it that way), and so the child would be either AO, BO, or OO. There's no other choice with an O parent. An O parent only has an O to give, and the AB child needs to get an A and a B, one from each parent.

The easiest way to understand it is to look at a picture. There's one in the source link at the bottom that has a chart so you can look up both parents and find out about the child. The site also explains why ABO blood typing is not an absolutely reliable test of parenthood, and it explains how the rh factor (the + or -) works. The baby does not have to be the same as either of its parents. Be careful. A lot of people who think they understand this really don't.

Either through the placenta or in the birth process when tissues are torn and the baby comes into contact with the mother's blood.
