Fig. 1: Nucleotide diversity (yellow), linkage disequilibrium (LD) (blue) and the cumulative length of centromeric satellites LmegCenR1 and LlusCenR1 (magenta) in 50 kb sliding windows along four largest nightingale chromosomes.
From: Germline-restricted chromosome of songbirds has different centromere compared to regular chromosomes
Chromosome morphology classifications adapted from Poignet et al. (2021). Black dots mark the positions of centromeres estimated from the cytogenetic data. The estimated positions of centromeres roughly colocalize with the genomic regions of decreased nucleotide diversity and elevated linkage disequilibrium and with the regions containing CenR1 repeats.
