Question: What is genotype II?

ii – This genotype produces no protein (type O). So, your blood type does not necessarily tell you exactly which alleles you have. For example, a person with blood type A could have either two iA alleles or one iA allele and one i allele.

What is blood type II?

Ii blood group system, classification of human blood based on the presence of antigens I and i on the surface of red blood cells. The Ii blood group system is associated with cold antibodies (antibodies that function only at temperatures below normal body heat) and several blood diseases.

Is a genotype 2 letters?

genotype = the genes of an organism; for one specific trait we use two letters to represent the genotype. A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).

What is the genotype of type A blood?

If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative.

Why do genotypes have 2 letters?

The two letters in a genotype represent the pair of alleles. The uppercase letter represents the dominant allele and the lowercase letter represents recessive allele.

Which allele is always written first?

The alleles are represented by letters. The letter chosen is usually the first letter of the trait.
