Abstract
From calculations on the standpoint of genic equilibrium, authors obtained the following results; diathesis of susceptibility to tuberculosis is inherited by two recessive independent genes a and b, a is of severe illness, of which the homozygotes fall ill entirely, b is of mild illness, of which bb individuals fall ill with some genotypic morbidity α. The frequecy of aa is 0.044 and that of bb is 0.21.
