    Nicht auf Lebensauslese, sondern auf Fortpflanzungs- und Fruchtbarkeitsauslese setzt die Eugenik ihre Hoffnung

    In a biological sense there is […] only one kind of selection, namely, fertility-selection

    With positive fertility selection the deviation is of great significance, but with partial negative selection the deviation is slight and with total negative selection the formulae give the same result. We have spoken of “lethal” selection and “fertility” selection. The difference is of course that in the latter case the partner who is married to a character-bearer is also affected by the selection. In the former case the character-bearer dies.
