if an individual has only one a gene, the excess b chains form the unusual tetramer b4, which causes hemoglobin H (HbH) disease. The complete absence of a genes results in hydrops fetalis, which is fatal at or before birth.

If entire genome is encoding than mathematically human should have 106 genes but humans have only 30,000 to 50,000 genes this is also a paradoxical feature of genome
