Polymorphic heterochromatic segments in Japanese quail microchromosomes.


Using highly extended lampbrush chromosomes from diplotene oocytes, we have examined the distribution of heterochromatin protein 1 beta (HP1 beta) and histone H3 modifications on chicken (Gallus gallus) and Japanese quail (Coturnix japonica) (2n = 78) microchromosomes. Acrocentric microchromosomes of chicken and submetacentric microchromosomes of quail… (More)
