This page wouldn't make any sense unless we know what the word 'allele' means. An allele is an alternative form of a gene that determine seperated traits that can be passed from parents to offspring. When the gene for one trait exists as only two alleles, there are 3 possible genotypes & 2 possible phenotypes. Three different genotypes come from the combination of alleles and two different phenotypes are the the dominant ones and the recessive ones. As you can see from the picture on the right -->

'Multiple Alleles' a single gene that have many possible alleles.  Good examples of multiple alleles inheritance are human blood types and skin colors.

Blood types have four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type. We typically call these alleles " A ," " B ," and " O ," but we usually write them with the letter I, which stands for immunoglobin. The alleles are as follows: IA for Type A blood, IB for type B blood and i for type O blood. And the allele for "O" (i) is recessive to the alleles for A and B. With three alleles we have 6 possible genotypes and 4 possible phenotypes. You can see the result from the chart below

**8:51 PM ** __** Notes about blood type **__

-There are 6 different genotypes -There are 4 different phenotypes -There are 2 genotypes for both A and B blood--- either homozygous (IAIA or IBIB) or heterozygous with one recessive allele for O (IAi or IBi). -The only genotype for O blood is homozygous recessive (ii). __**What is blood made of? **__

There are three kinds of cells in the blood: red blood cells, white blood cells, and platelets. //Red blood cells// carry oxygen. //White blood cells// fight infections. //Platelets// help blood to clot.

__ Blood Types in the U.S __. **// VS //**. __ Blood types in Thailand. __

O 44% > O 38% A 42% > A 34%

B 10% > B 21%

AB 4% ---> AB 7%

//** How is blood group O the most common if the allele for O is recessive? **//

Because it's not determine on dominant or recessive traits. You can see that some diseases are dominant traits, but still rare in the world.

//** Eat right for your type! :) **//

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 110%;">If you're blood //**type O**//, you should not eat too much grains and breads. And exercise twice a week. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 110%;">//**Type A**// Eat lots of vegetable and grains! <span style="font-family: Arial,Helvetica,sans-serif; font-size: 110%;">//**Type B**// should eat low-fat dairy and meat but avoid wheat, corn, and lentils. Blood type B people can exercise but not too much. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 110%;">The blood //**type AB**// should not eat chicken, beef, and pork but you can eat seafood, tofu and dairy.

//**<span style="color: #000000; font-family: Arial,Helvetica,sans-serif; font-size: 110%;">Blood as one of the most helpful keys in the crime scene. **//

<span style="color: #000000; font-family: Arial,Helvetica,sans-serif; font-size: 110%;">Blood is the most common bodily fluid at the crime scenes. It's one of the most helpful key because the blood that left at the crime scenes can tell what happened and when were the crime took place. If the blood is in liquid form, then the bleeding only happened just few minutes ago! But if it shiny and nearly dry, it happened less than an hour ago. And if the blood is saperated into a clot, it happened saveral hours ago. Moreover, blood can tell the diseases, drugs or alcohol that were in the victims.

[|Information on Blood]- Boone, This site tells about what is in blood, types of blood and how blood is produced. [|My Blood, Your Blood] This is a link that has a lot of information on blood types, parts, and processes. It includes the history and new research of blood and also has some media on it. - Jason Van Winkle
