Recombinant segregation patterns. Nomenclature used to describe meiotic recombination events in eight-spored fungi is adopted to characterize equivalent outcomes for gene targeting with a sequence insertion vector. For each segregation class, the double-strand product is represented in a more simplified, single-strand form in parentheses, a scheme adopted in Figures 4–6 and 8. Refer to text for details.
