What was discovered
Van Beneden showed in Ascaris that gametes have half the number of chromosomes and that fertilisation restores it; Weismann predicted the need for this reduction and the continuity of the germ plasm.
What it led to
- chromosome theory
- genetics of recombination
- rejection of the inheritance of acquired characteristics (Weismann)
Built on
- Mitosis and chromosomes (Flemming)1879-1882
- Flemming's mitosis
- fertilisation observed by Hertwig
