DOI: 10.1073/pnas.2103960119
Abstract: Significance Most if not all songbirds possess a germline-restricted chromosome (GRC) which is believed to be exclusively maternally inherited. However, we show that, in the zebra finch, the GRC can also be paternally inherited and… read more here.

DOI: 10.1093/molbev/msad096
Abstract: Abstract The germline-restricted chromosome (GRC) is likely present in all songbird species but differs widely in size and gene content. This extra chromosome has been described as either a microchromosome with only limited basic gene… read more here.

DOI: 10.1159/000524681
Abstract: Karyotypes of less than 10% of bird species are known. Using immunolocalization of the synaptonemal complex, the core structure of meiotic chromosomes at the pachytene stage, and centromere proteins, we describe male pachytene karyotypes of… read more here.

DOI: 10.1371/journal.pbio.3001559
Abstract: Germline-restricted DNA has evolved in diverse animal taxa and is found in several vertebrate clades, nematodes, and flies. In these lineages, either portions of chromosomes or entire chromosomes are eliminated from somatic cells early in… read more here.
