Intercalary heterochromatin of Drosophila as a potential model for human fragile sites.
We summarize our proposal that "intercalary heterochromatin" of Drosophila is a useful model for human fragile sites. Comparison with Drosophila site 11A suggests that the normal allele of fragile site Xq27 is a meiotic pairing site.
