Table I. Pollen viability in the ech mutant.
Tetrad analysis is shown for pollen mother cell meiotic products in the wild type (qrt) and ech. In the qrt background, the tetraspores fail to separate, enabling the viability of the meiotic products to be determined (Preuss et al., 1994). [See online article for color version of this table.]
