Summary
An account is given of possible deviations in cell or nuclear divisions before, during or after meiosis resulting in homozygous or heterozygous diploid products of gametogenesis.
After research on matromorphic plants for qualitative characters it appeared that part of the plants were heterozygous for these characters.
From the results of this research it may be concluded that it is not unlikely that matromorphic embryos develop from egg-cells which were diploid as a result of different deviations in cell or nuclear divisions.
