Abstract:
Meiotic recombination in the mouse is sometimes restricted to specific chromosomal sites. For example, when recombinants within the I region of the mouse major histocompatibility complex (MHC) are examined, the breakpoints between standard alleles can usually be mapped to the Eb gene. DNA sequence analysis of five cases of meiotic crossing over associated with this gene suggests that the recombinational hot spot may be confined to large regions of nucleotide identity located within the second intron of the Eb gene.
