All posssible blood groups of babies born to both parents of O+ve blood group.? Whether B-ve group possible?

Answer 1

If both parents are O type, then the child would also be O. The child could be O+ or O- but B- is not possible.

If the child is B-, then one parent would have to be either AB, B (either positive or negative)

Answer 2

O+ve is the most common blood group of all.

If the parents are both O+ve then the baby will most definately be O aswell - there are NO alternatives, despite what some of the graphs may say, it simply isnt possible. One of the parents would have to be B or AB to result in a B baby. The confusion comes in because an A or B parent could have a O baby.

There is a chance that the baby could be -ve, but its most probably +ve.

Blood groups are inherited as follows;
O ~ O = O
O ~ A = A or O
O ~ B = B or O
O ~ AB = A or B
A ~ A = A or O
A ~ B = A or B or AB or O
A ~ AB = A or B or AB
B ~ B = B or O
B ~ AB = A or B or AB
AB ~ AB = A or B or AB

The rhesus factor is calculated seperately.
-ve ~ -ve = -ve (100% babys -ve)
+ve ~ -ve = +ve or -ve (either 50% or 100% babys +ve)
+ve ~ +ve = +ve or -ve (either 75% or 100% babys +ve)
Where it can be +ve or -ve it is twice as more likely in each case that the baby will be +ve. Example~out of 3 babys born to +ve parents 2 of them will have a 100% chance of being +ve & only one will have a 75% chance of being +ve.

The reason for the variation in the percentages is because people with +ve blood may also 'carry' the -ve. The percentages are exact. That mean that in the situation you outlined. If both +ve parents 'carried' the -ve then there is a 75% chance the baby will be +ve, but if only one or none of the parents 'carried' the -ve then 100% of the babys will be +ve too.

Answer 3

Your question is not so clear.Ill try to explain but if I lose you you'll have to ask a doctor.
If the mother is neg and the baby is pos the mother will build up antibodies that could kill a second baby. The same would be if baby is neg and mother pos. Some genes are recessive.Only a dominant gene will stand out.
example, two brown eyed parents can have a blue eyed baby. Brown is dominant so that's what you see. But the baby could inherit the two blue eye recessive genes and have blue eyes. Two blue eye parents cant have a brown eye baby because it takes two blue eye genes to make blue dominant.
There a 4 blood groups A,B,AB and O.There is Rh positive and Rh negative.They are two different sets of genes. Do you doubt that the baby is yours? Don't let blood types feed a doubt. If you have doubts get a DNA test.

Answer 4

There are 3 genes for blood 0, A, and B. O is recessive, A and B are co-dominant. You get 1 gene from each parent - thus you have 2 blood genes. Below shows what bllod group you should be depending on the 2 genes you inherit...
O+O = O
O+A = A
O+B =B
A+A =A
B+B =B
A+B =AB

HOWEVER, genetics can do funny things like skipping generations - so it's not impossible for a B baby to be born to 2 O parents - unlikely - but not impossible.

Answer 5

Unless the mail man had something to do with it, the child of two parents who are both O + will be either O+/- depending. Either way, the child will be O. No other possibility exists (unless the mail man delivered more than just the mail).

Answer 6

<>No. Only O (whether + or -) can be born to 2 O parents. No way can a B be born to 2 O parents....impossible.

Answer 7

An infant born from both parents O, has to be an O. it comes with the gen. but there's noway to forecast the rhesus (rh+ or -).

Answer 8

No, its not possible the child can only be o.
