Answer:
ii, or Ii
Step-by-step explanation:
The genotype refers to the genetic makeup of an individual, which determines their physical and biological characteristics. Blood type is one of the many traits that are determined by an individual's genotype. The blood type O is determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. People with blood type O have neither A nor B antigens on their red blood cells. Instead, they have the "O" antigen.
The genotype for blood type O can be represented by the letters "IA" and "IB", where I is the gene that codes for the A and B antigens, and A and B are the alleles that determine the presence or absence of these antigens. People with blood type O have two "i" alleles, which are recessive and do not code for either the A or B antigen. So, the genotype for blood type O is ii, or Ii.
