From Embryology
It is very simple to tell what the kinds of genetic offspring will be when any one of these sixteen individuals marries any other one. These possibilities are summarized in the following statement taken from Ottenberg :
Unions of I and I give I
I "1 I II II II) '
^ "M I III III III ) ^' ^^^
Unions of II and III give I, II, III, IV IV I I, II, III, IV
IV II I, II, III, IV
IV III I, II, III, IV IV IV I, II, III, IV
Two actual pedigrees, one of them carried through three generations, will serve to illustrate particular cases (fig. 76).
