The genes for the others work in similar fashions, though certainly not all have three alleles. The other aspect of blood type which is of most interest to us is the Rh factor. Genetically, this is much simpler than the ABo system. It has only two alleles, one dominant (Rh-positive) and one recessive (Rh-negative).
What else can I help you with?
What blood types can be formed by crossing A genes with B genes?
Crossing A genes with B genes can produce offspring with blood types A, B, AB, or O. The A and B genes are codominant, meaning they both express themselves in the AB genotype, while the O gene is recessive to both A and B.
What type of gene is a master control gene that directs development of body parts in specific locations in many organisms?
The gene you are referring to is called a Hox gene. Hox genes are a class of master control genes that play a critical role in determining the body plan and specifying the identity of body segments during development in many organisms.
How can one determine blood type from parents?
Blood type can be determined from parents by looking at their blood types and using the principles of genetics. A child's blood type is determined by the combination of blood type genes inherited from their parents. For example, if both parents have type A blood, their child could have either type A or type O blood. If one parent has type A blood and the other has type B blood, their child could have type A, type B, type AB, or type O blood.
How do you get O- blood type?
O- blood type is inherited when both parents pass on the O- gene to their child. This means that a person with O- blood type must have two parents who are either O- or have O- genes.
Where did you get your a positive blood type?
I know a lot about blood types but I don't understand wat ur asking you get ur blood type in your genes but I don't know if that is wat ur asking
How many different genes control the blood type of an individule?

How many genes are there for blood type?
There are three
What type of gene is master control gene that directs development of body parts in specific locations in many organisms?
There are several:Master control genes or homeotic genesHox genes (from an abbreviation of homeobox)
Does everybody in the same family have the same blood type?
Not everyone in the same family has the same blood type. There are two separate genes that determine the blood type a person will have. One is for type such as O, A, AB, or B. The other determines if the blood will be positive or negative. It depends on which genes a person is born with. Both genes are on different chromosomes.
If a father is a plus blood type what type would his children have?
Blood type is a combination of the mother's and the father's genes.
Is blood type inherited through genes?
Yes
How could parents with blood type A and B have a child with blood type O?
If both parents had heterozygous blood-type genes, then the child could inherit the recessive O type from each parent. Suppose the mother had the genes for A and O, and the father had the genes for B and O. They would then have blood-types A and B respectively. Depending on which parts were passed to the child, any blood type would be possible.
How many alles control blood type in humans?

Man blood type B woman blood type AB what would Childs blood type be?
There is no definite answer to this question. It would all depend on which genes the child would get. The child could have more of its moms genes or more of its dads genes or equal! It also has to be known whether the parents have positive or negative blood.
What type of blood will a child have if both parents are positive types?
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
What blood types can be formed by crossing A genes with B genes?
Crossing A genes with B genes can produce offspring with blood types A, B, AB, or O. The A and B genes are codominant, meaning they both express themselves in the AB genotype, while the O gene is recessive to both A and B.
