1. A method of differential detection of target sequences in a mixture of maternal and fetal genetic material, comprising the steps of:

  • a) obtaining maternal tissue containing both maternal and fetal genetic material;

    b) distributing the genetic material into discrete samples, each sample containing on average not more than about one target sequence per sample;

    c) measuring the presence of different target sequences in the discrete samples; and

    d) analyzing a number of the discrete samples sufficient to obtain results distinguishing different target sequences.
