is the blood type for a baby determined by the male?

i think it is by both

The blood group of parents do not determine the sex of the child just the blood group of the child. Both my parents are O+ve, and i have got a brother. Its just the chromosomes X and Y that determines the sex in humans.

Your blood type depends on the blood type of your parents. So if their bloodtype is known you can make a good guess of your bloodtype. \nBut to be ascertain you'll have to get pricked .. Btw .. it doesnt hurt or something .. they just take a droplet of your blood for this test ..

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

(1) You can donate even without knowing your Blood Type.\n(2) Blood Group test is performed at almost every hospital. Result is obtained very shortly which allows you to know the type of yuor Blood Group.

The blood type O means that there are no A proteins or B proteins attached to the outside of your mom's blood cells.  Your dad's blood cells have both A proteins and B proteins.  Since each of your parents passes down one gene for blood type to you, your mom just gave you the smooth O cells.  Your dad could either have passed down A cells or B cells.  You ended up with a B from Dad, an O from Mom and a + from both.  Makes perfect sense!

Blood is everything!! You do not want children with problems, do you?\n\nFor your blood type, your best match is: \n\nType O\n\nA+ and B+ can cause hemogoblinia, which causes small stature in offspring and can cause clawlike hands to form\n\nA+ and A can cause 'Vampirism' which results in offspring that tends to stay out late, wear dark clothes, and engage in orgiastic bloodletting parties.\n\nO is the 'black' of blood. It goes with everything.

In the ABO blood type system, each person has 2 blood type alleles, one from each parent. The alleles can be A, B, or O. Which 2 alleles you have determines which blood type you will be: AA or AO is blood type A; BB or BO is blood type B; OO is blood type O; AB is blood type AB.\n\nThe +/- system is called the Rhesus factor and works in a similar way. There are 2 alleles: Rh+ (+ for short) or Rh- (- for short). A person with 2 copies of Rh+ (++) or only 1 copy (+-) will be +. A person with no Rh+ (--) will be -. \n\nTo answer your final question, a person who is O+ must have the alleles OO++ or OO+-. A person who is A+ can be AA++, AO++, AA+-, or AO+-. They can certainly share the same mother and father. One example is that the mother can be AO++ and the father is AO+-.

Can a man have, let's say, B+? Yes.\nCan a woman have, let's say, B+? Yes.\nCan they get married? Yes.\n\nExact same blood type will not be a problem. Only way for problem is if baby is + and mom is -. Only way for that to happen is if Dad is + and mom is -.

It is determined by the sperm cell involved in the conception.\n\nThe sperm cell carries either an X chromosome or a Y chromosome (remember that dad is male, so he has XY).\n\nThe ovum (egg cell) always carries an X chromosome (mom is XX).\n\nSo if the sperm cell carries an X chromosome, the resulting embryo is XX, and will develop into a girl.  If the sperm cell carries a Y chromosome, the resulting embryo is XY, and will develop into a boy.

Blood type has to do with chemical markers on your cells called antigens. People with type A blood have A antigens, and people with type O blood have no antigens. A person has two genes controlling blood type, one from each parent. Both your parents have the genotype AO. Because they have the gene for A, they produce the antigen for that blood type. However, you inherited the recessive gene from both your mother and your father (genotype OO) and therefore have no antigen-producing genes. This makes you type O.  \n\nTherefore, if your spouse also has type O blood, then any chidren you produce would also have to be type O. The person above me is either mistaken about her parents' bloodtypes or the identity of her parents.\n\nThe RH factor (+/-) works in a similar fashion.

It is not possible for a child of two O+ parents to have A+ blood.\n\nThe Rhesus factor (Rh) positive is not a problem - only one parent has to be positive.\n\nHowever, blood groups A, B, AB and O are determined by autosomal dominant transmission - this means that you only have to have one copy of the gene in order to express the trait, and they are not on the sex chromosomes, so both male and female children have equal chances of getting them.\n\nThe "A" and "B" just refer to two different proteins, called A and B (surprise). If you have one copy of the gene, YOU WILL HAVE THAT BLOOD TYPE. The only way to have O blood is to have two recessive O genes. Both parents *have* to be genotype OO. If they have one O and one A gene, then they will be blood type A.\n\nSo, if both parents are O, the ONLY possible blood group for their children is O. If the mother is O and the child is A, the father MUST be A.

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.

in order for a child to have O blood, both parents must have one O allele (because O is recessive so the child needs 2 O alleles). Since we know that the father definitely has one A and the mother has one B, the parents' genotypes are\nmale: AO\nfemale: BO\n\n\nAO x BO\n\n-------A------O\n---B--AB----BO\n---O--AO---OO\n\nI hope you could understand my punnett square; using dashes for spacing is ugly! Their children will have 25% chance of AB blood, 25% A (genotype AO), 25% B (genotype BO), and 25% O.

yes they can, the Rh is made up of two alleles and the baby receives one from each parent. If both parents are heterozygous for the d gene then the baby has a one in foud chance of being RhD negative

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!!!
