to what? have four children with four different blood types?\n\nYes, theoretically. Depending on the full genotype of the mother and father, but if they are both heterozygous (i.e., if Michelle's genotype is AO, and Mike's genotype is BO), then the possibilities for children include:\nAB\nAO\nOB\nOO\n\nIf they are both homozygous, however (ie, AA and BB), all their children will be AB. \n\nAnd then of course there are various combinations if Michelle is AO and Mike is BB or Michelle is AA while Mike is BO. A punnet square will help you out there.

Let's take the Blue eyes - brown eyes example.  Brown is the dominant trait, so we'll use the capital B letter.  Blue is the recessive trait, so we'll use the b letter.  A person with blue eyes has the genotype bb (got a b from dad and a b from mom).  A person with brown eyes can be homozygous BB (got B from dad and B from mom) or heterozygous Bb (got B from one parent and b from the other parent).\nA first generation usually starts with pure breeds, so both homozygous.  We'll have BB and bb as the starting parents.  Those parents produce gametes in their gonads.  Let's say that mom has blue eyes and dad has brown eyes.  All her eggs will have the b gene as all dad's spermatozoids will have the B gene.  If you want to make the Punnett square, you'll find that all babies will have 100% probability to be Bb\n____|__B__|__B__\n__b_|_Bb__|_Bb__\n__b_|_Bb__|_Bb__\nThe second generation is made by taking two of those offspring and crossing them.  First, you have to find out what alleles will be in the gametes.  Half of the eggs will be b and half will be B.  Also, half of the spermatozoids will be B and half will be b.  In the Punnett square you'll have.\n____|__B__|__b__\n__B_|_BB_|_Bb_\n__b_|_Bb__|_bb__\nHere, the babies will have 25% chance to have blue eyes (bb) and 75% chance to have brown eyes (25% homozygotous BB and 50% heterozygotous Bb).

Yep, we each have two set of chromosomes (genes), one from each parent. There are dominant genes and recessive genes. Mother has an A gene (dom) and a O gene (res), father has a B gene (dom) and O gene (res). The child can have one of 4 blood types A ( A mother, O father), B( B father O mother ), AB ( A mother, B father ) and O ( O mother, O father ) The negative works the same with + being dominant, but both parents are negative.

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.

no doesnt matter as far as blood groups go. AB, B, O whatever theyre all just as good. \n\nhowever, genetic testing to see if people carry a rececive gene that could result in diseases like cystic fibrosis or tay-sachs might be a good idea.... but you could always adopt or hope your kids dont get those diseases, so i wouldnt look to far into it. plus you might scare off your girl if you make her get all kinds of blood tests before you get married

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.

The women and the man would have a heterozygous geneotype\n\nThe woman's genotype would consist of a gene for B blood and for O blood.\nThe man's genotypes would consist of a gene for A blood and B blood.  \n\nSince O is a ressisve gene, A and B would dominiant the blood type for their children who could have an A, B or AB blood type.  \n\nFollowing a basic 2 x 2 Punnett square, the statistics of a child getting a homozygous B blood type would be 1/4; a AB blood type would be 1/4; for getting a heterzygous A or B blood type with a ressive O gene would be 2/4 or 1/2.

2...one is father...other is son....\n\nmuahahahahah

YES. Absolutely, despite all the answers you've received to the contrary. \n\nThe way blood groups are named, either your blood contains certain proteins (named A and B) or it doesn't - if you have both you are blood type AB; if you have only A you are A; if you have only B you are, you guessed it, B, and if you have neither you are blood type O.\n\nIf you have a gene for a blood protein, either A or B, you will have that protein in your blood. However, we have two copies of each chromosome, and it is possible that each parent has one copy of the A gene on one chromosome, and doesn't have it on their other chromosome (O). This means they will both be blood type A, since they each have one copy. However, if they have a child who happens to get the O chromosome from each of them, then the child will be blood type O. Mathematically expressed, each parent is AO, and on average their children have a 25% chance of being AA (blood type A and cannot have type O kids), 50% chance of being AO (blood type A but able to have type O kids), and 25% chance of being OO (blood type O).\n\nThis is the whole idea of recessive genes, which also explains why two brown-eyed people can have a blue-eyed baby without any hanky-panky going on.\n\nAs regards the Rhesus factor, i.e. the "+", again that is a recessive characteristic. The child must have received the Rh factor from his father, since his mother is negative. (NOTE that any Rh-negative woman who has an Rh-positive baby should get a shot of something called RhoGam, or WinRho, to prevent problems in future pregnancies.)

Yes.  Your child may be A+, O+, A-, or O-.  The + part of the blood type is dominant to -.  You and your husband would have to each have a + from one parent and a - from the other parent in order for your child to receive 2 - genes and have rh- blood.  Having a different bloodtype than your child can lead to serious complications, especially during the second pregnancy.  If during the birth of your first child, your body is exposed to your baby's blood (and the blood is a different type than your own), you may build up antibodies to your baby's blood.  If your next child has the same bloodtype as your first child, your body may actually attack the baby.  Be sure to talk to your doctor about bloodtype dangers.
526088
YES,  yes,  yes.\n\nThe father  CAN  be blood type "O" and the mother\ncan be blood type AB. The baby will be A or B.\nSince the father thought his type was O, something is amiss.

WWWwwwilbuuur. Naay. Lookin good my man. I say they should get married, huh? Poor Michael; who would love him in that marriage? Would they both be in love with Paris? Can you imagine their children? Probably make you seem like a model. Michael would probably get all upset with Hilton about sex though. He'd be complaining about how much noise she made during sex and how he could hear it all the way from his room. Yep, she's a nasty one and certainly not the lessor of two evils. Oh, can I get you an apple?
