Blood type |
- Is determined by the membrane protein on the surface of red blood cells - I-gene determines which proteins are produced to the RBC. - 3 versions of I-gene: • IA types A-protein • IB types B-protein • i types no protein at all - humans have 2 copies of alleles: one from mom, one from dad. |
|
|
Homozygote |
Both alleles are the same ones e.g IAIA |
|
|
Heterozygote |
Alleles are different e.g IA IB |
|
|
Recessive allele |
Repressed and retreating allele |
|
|
Dominant allele |
Overpowering, controlling the recessive allele |
|
|
Phenotype |
Genotype + influence of an environment > external appearance of an individual |
|
|
Genotype |
Genes from parents form the genome of an individual |
|
|
Codominant alleles |
Both alleles are expressed independently e.g IA IB |
|
|
Agglutination |
Clumping of the blood cells |
|
|
How does it work? |
The same blood types can give the blood to each other but different blood types with different membrane proteins can't be mixed because body/blood will not recognize the other protein so it clumps up and destroys unfamiliar proteins = Agglutination |
|
|
Rhesus blood group |
- Some ppl have Rh (D) antigen on the surface of their rbc and some don't - if you have it, your blood type is positive, if you don't, your blood type is negative - E.g if you have alleles IB IB => B-proteins AND then also Rh(D) antigen => + SO your blood type is B+. |
