the human blood type is controlled by the gene 'I'. It is of 3 types Ia, Ib and i. the alleles 'Ia' and 'Ib' produce slightly different sugar polymers protruding on its surface while the 'i' doesn't produce any sugar polymers. as humans are haploid the contain 2 alleles out of the 3 I gene alleles, as the individual alleles come from the parent gamete. the alleles 'Ia' and 'Ib' are completely dominant over 'i', i.e, if alleles 'Ia' and 'i' are present then only the allele 'Ia' will be expressed, and the same for 'Ib' and 'i' happens, but when 'Ia' and 'Ib' are present together then they both express their own types, this is because of the co-dominance.
Ia + Ia = IaIa = A
Ia + Ib = IaIb = AB
Ia + i = Iai = A
Ib + Ia = IbIa = AB
Ib + Ib = IbIb = B
Ib + i = Ibi = B
i + i = ii = 0 (zero commonly known as O)

How many genes are there for blood type?
There are three
Are hereditary information stored in ribosomes with chromosomes that have many genes?
Hereditary information is stored inside the nucleus, which does have chromosomes that contain many genes. DNA is an important part of determining who we are.
How many genes does a female have for a blood clotting?
Since we can never be sure that we know everything about the mechanisms behind blood clotting and there may always be just another protein involved in it, there is at the moment no definitive answer to this question. Even if we could be sure that our knowledge is comprehensive, it would still be difficult to define exactly which genes are "for blood clotting" and which aren't, as many genes contribute indirectly to blood clotting. There is however no reason for there to be a difference between males and females in this number. If you are considering only the main clotting factors (tissue factor, VII, X, prothrombin, V, VIII, IX, fibrin and XIII), these are 9 genes.
How many different genes control the blood type of an individule?
4
What is Polygenic Inheritence?
Polygenic inheritance is the phenotypic expression of a trait involving the interaction of many genes.
Why does the y chromosome not carry any alleles?
The Y chromosome is smaller than the X chromosome and contains fewer genes. It carries the genes necessary for determining male sex and some other genes, but it lacks many of the genes present on the X chromosome. This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.
How many people were involved with the blood diamond?
Since this is an illegal activity, it is not possible to estimate the population involved.
What is involved in donating bone marrow and what are the odds of a match?
Their are many things that are involved in donating bone marrow. Some things that are involved are money, blood and many more. The odds of a match are less than 25 %.
How many genes are there in DNA?
Different species have different numbers of genes. About 1.5% of human DNA is genes - and it is estimated that there are around 23,000 protein-coding genes.
What is the amount of genes in a human cell?
About 35,000 genes per body cell. Note: sex cells differ.
Who are affected by blood diamonds?
Everyone involved in blood diamonds, from the terrorists who force people to mine them by hand, those terrorized people -- and their families, and the traffickers involved, is affected: many with death, mayhem and other inhumane acts.
What to genes do?
Genes, or genetic material, are basically instructions encoded in DNA for building cells in an organism. Genes code for many different traits like blood type, hair color, and skin color. Scientists frequently debate the role of genetics in behavioral traits, the nature vs. nurture argument. Currently it is unknown to what extent genes code for things like violence or altruism.
