The difference in blood types between you and your twin brother is likely due to the specific combination of alleles inherited from your parents. Blood type is determined by the ABO gene, which has three main alleles: A, B, and O. If one parent carries the B allele and the other carries the O allele, you could inherit a B allele, resulting in a B blood type, while your twin brother could inherit two O alleles, resulting in an O blood type. This genetic variation is possible even in identical twins due to the random assortment of alleles during fertilization.
