Question

If Le gene inherited, person has Lea adsorbed ontro RBCs

Answer 1

If the Le gene is inherited, the person has
`Le^a` adsorbed onto red blood cells (RBCs).

Step-by-step explanation:

The Lewis blood group system is determined by the inheritance of Lewis genes (Le and le). The Le gene is responsible for the synthesis of Lewis antigens, and if inherited, it leads to the expression of
`Le^a` antigen on the surface of red blood cells (RBCs). Lewis antigens are glycoproteins found in various body tissues, including RBCs.

The Le gene undergoes complex interactions with other blood group systems, such as the ABO system. The expression of Lewis antigens is influenced by the presence of the H antigen, which itself is influenced by the ABO blood group. Individuals with
`Le^a`antigen on their RBCs may be Le(a+b-) or Le(a-b+), depending on the interaction with other blood group antigens.

In summary, the expression of
`Le^a o`n RBCs is determined by the inheritance of the Le gene. Understanding the genetics and interactions of blood group systems is essential in transfusion medicine and plays a crucial role in blood compatibility assessments.
