...Hall put these prenatal stepchildren into his tub and gave them the bell treatment. All had convulsions; two-thirds died. None behaved like noise-resistant black mice. This indicated, said Dr. Hall, that the tendency to die of audiogenic seizures is hereditary, carried by a gene in the germ plasm...
Final problem: Was this gene a "dominant" or a "recessive?" To find out, Dr. Hall mated brown mice with black mice. When their hybrid offspring were tried in the tub, nearly all died in convulsions at the sound of the fatal bell. This proved (according to Mendel's law of heredity) that the jittery gene was dominant. A recessive gene would not have expressed itself until the next generation...
