COVER DNA sequence information from the genome projects in combination with microhybridization technology allows heritable variation to be assessed with new ease. Oligonucleotide arrays were used to genotype ~3800 markers in the four meiotic products from a cross between two yeast strains. Recombination events between DNA strands (crossed lines) for the 16 chromosomes are depicted. See page 1194.[Image: E. A. Winzeler]
