Can an O + (positive) mom and a B+ (positive) dad, enjoy a B - (negative) child?
Answers:
It is possible. All human had a double duplicate of equal gene, duploid. eg: gene for blood type. Since mom blood is O+ that means she get both O blood gene, it might be O+:O+ or O+:O-.
As for the dad, Since he is B+, that means his gene could own B+:B+ or a B+:B- genes or even B+:O+/-
However egg and sperm cell consisted of haploid chromosome (single chromosome) because of the meiosis process. So some of mom egg cell might contain only O+ and some O-. Same entry happen for dad's sperm which might consist of B+ and some B-.
So if B+ sperm fertilize O+ egg we get B+ baby.
If B+ sperm fertilize O- egg we still get B+ baby (because O and -ve are recessive gene and B+ is dominant gene)
Same article happen if B- sperm fertilize O+ egg; we still get B+ baby.
If B- sperm fertilize O- egg, we will carry B- baby.
However nearby is still chance for the little one to be O+/- is the father is a B+:O+/- , since O+/- sperm fertilize O+/- egg will produce O-/+ baby.
So base on the dominant and recessive behavior of genes we can deduce that near is 1/8 of a change the babe will be B-, 1/4 of chance it might be O-/+ and 5/8 break it will be B+
it's possible, but not likely. the + is dominate unless you also convey the recessive gene and the kid got the double recessive that overpowers the "stronger" +
cautious
yes
my doctor says no but i dont have an idea that he knows what hes chitchat about im 0+ and my sons father say hes 0+ but my son is A- and my father was A- and so be every one in his relatives
Yes. Rh-negative factor is recessive and both parents have to get the gene for the child to have it. If 2 Rh-positive parents own an Rh-negative child, then that is to say proof that both parents carry the Rh-negative gene.
Absolutely. The ABO blood groups are determined base upon the presence or absence of the A antigen or the B antigen. When neither are present the creature is type O. THey are known as co-dominant, so if you own one gene for A and the other gene is for B then you are type AB. The Rh factor also depends upon different antigens surrounded by which the Rh + antigen is dominant. So, if you are Rh + / Rh - then you are Rh +:
As follows for Rh:
+ / + = +
+ / - = +
- / - = -
The type O Mom have no ABO antigens and the type B Dad must be heterozygous for B and O. Both of them must be heterozygous for Rh +, so they would both be + / -..
So Mom = O / O :: + / -
and Dad = B / O :: +/ -
Their children can be either type B+, type B -, type O + or type O -.
Yes,don't you verbs.Because of the fact that + is dominant and if one your grandmother or grandfather on respectively side(mother and father's) was refusal,then respectively of your parents carry +/- genotype,and likelihood are only 25%,but yes if you adjectives both -/- genes from each of your parents.
the mom and dad must hold +,- genes, and then both of their genes must combine so that the child have -,- genes (I'm a living example!)
sorry, can't be to specific. its been to long since I took a biology class.
Yes it is possible. The removal of RH factor (RH-) is a recessive trait and it is very possible for two RH+ parents to both convey the recessive trait. If both parents carry the trait here is a roughly 1 in 4 adjectives that a child will be RH-.
If both parents are +/-, there would be a 25% casual of having a - child.
no..if both parents r Rh+ later all their children should be Rh+ coz it depends on the presence or nothingness of the D gene..and there is no d gene.
around the one that said that his son is Rh - although he and his wife are +s.i think he have to look for the real father!
Yes
the genotype for you would be
OO +- expressed as Opos
The genotype for him could be
BB +- or BO +-
You can solely give the O gene and any + or - Rh
He can give B or possibly O gene and any + or - Rh
His B gene (with your O gene) and an - Rh gene from both of you will result in a B- child
