However, this easy scheme cannot deal with intercourse reversals and intersexes and you can hermaphrodites, which show that both males and females support the potentialities to own each other version of intimate distinction. There are two alternatives of hypothesis. These root buildings are subject to the fresh new „realizers” aa and you may yy that are contained in the sex chromosomes and you may operate especially with the AA and you can GG.

Therefore inside the male step one Bauch 1930, 1931. Correns 1928a. Both of these sets regarding products act of the stimulating the root potencies toward two types of distinction, that are thought by Goldschmidt as several effect- type of the machine general in the place of several specific complexes away from family genes. The newest stimulations considering the Yards and you will F situations is antagonistic together, together with outcome is determined by perhaps the M and/or F facts is actually healthier; ergo in case offered over the FF factors is actually healthier versus MM from the ladies, nevertheless Ff about men is actually weakened.
