it is postulated that ( 1 ) normal nuclear functioning requires a definite spatial organization of chromosomes , which is presumably achieved by chromosome-membrane associations , ( 2 ) chromosomes are inherited from the female parent with spatial ordering preserved , i.e . membranes and associated chromosomes are handed on directly from the female parent , ( 3 ) spatial ordering is not necessarily preserved in male gametes , and paternally derived chromosomes carry information enabling them to become correctly organized within the zygote nucleus , and ( 4 ) hybrid dysgenesis results when the chromosome ( s ) from the male of one strain lack the information to become correctly organized in the nucleus of a second strain .
