Some types of alleles are: blood type, hair color, hair type, eye color, etc.
Dominant alleles :-)
unlike alleles
There are three alleles for blood type: IA=Blood type A IB=Blood type B i=Blood type O The alleles for blood type A and B are codominant so when someone contains the IA and IB alleles, their blood type is AB.
* Type A alleles could be : IAIA or IAi* Type B alleles could be : IBIB or IBi* Type AB alleles : IAIB* Type O alleles : ii
Alleles Frequency
multiple alleles
Human blood type is determined by codominant alleles.
1-Type A ... which has antibodies : B ... and Antigene : A2-Type B ... which has antibodies : A ... and Antigen : B3-Type AB . which has No antibodies ... and has Antigen : A and B4-Type O .. which has antibodies : A and B ... and has No Antigens* Type A alleles could be : IAIA or IAi* Type B alleles could be : IBIB or IBi* Type AB alleles : IAIB* Type O alleles : ii

Everyone only has two alleles for blood type. The parents each pass one down to the child.
The three alleles are A, B, and O
Each person has two alleles for their blood type, one dominant and one recessive. Except for type AB blood where the alleles are co-dominant. The allele for O blood is always recessive when paired with either an A or B allele.
