Table 1 Partition of hybrid fragments after random reannealing of sibling pair DNAs.

From: Robust physical methods that enrich genomic regions identical by descent for linkage studies: confirmation of a locus for osteogenesis imperfecta

  Heterohybrid Homohybrid
  Maternal or Paternal Maternal/ Paternal  
  IBD Non-Identical   
All loci 1/8 1/8 1/4 1/2
Biparental IBD locus 1/4 0 1/4 1/2
Monoparental IBD locus 1/8 1/8 1/4 1/2
Non-identical locus 0 1/4 1/4 1/2
  1. Variation in the distribution of reannealed DNA mass depending on the class of locus sharing. The mass distribution for a monoparental IBD locus is the same as that expected for annealing of grandparent and grandchild DNAs.
