| Abstract: | In the mouse, offspring born from mature fathers exhibit better behaviouralperformances (for spontaneous activity in both sex and learning capacity inmales) than those born from post-pubescent fathers. These behaviouralvariations are not accompanied by other obvious modifications. They couldcorrespond to what has been observed in man relating to the results in apsychometric test undergone by male progeny born from very young to maturefathers. These data and those which show a decrease in mental performancein rats and human males born from mature to senescent fathers suggest theparticipation of some genetic factors in these phenomena. |
