Distribution of H4Ac, H3K9me3 and 5mC on chicken lampbrush chromosome W (GGAW). Immunostaining of GGAW with antibodies against H4Ac (a), H3K9me3 (b) and 5mC (c). a′, b′, c′ – DAPI staining of corresponding chromosomes. a′′, b′′, c′′ – merged images of corresponding chromosomes (immunostaining – red, DAPI – cyan). Scale bars – 10 μm. a′′′, b′′′, c′′′ – maps of corresponding epigenetic modifications distribution. Intensity of immunostaining and DAPI-staining pattern are indicated by colors as on Fig. 1a′′′, b′′′, c′′. Numbers (1–7) indicate individual chromomeres of GGAW from free terminus to chiasma with the chromosome Z. CEN – centromere position
