Occasional paternal inheritance of the germline-restricted chromosome in songbirds | PNAS

Songbirds have one special accessory chromosome, the so-called germline-restricted chromosome (GRC), which is only present in germline cells and ab...

Hi I’m a PhD student from Max Planck Institute for Ornithology. I’m excited to share our findings published at pnas.org/content/119/4/e2103…. With @fjruizruano @alexander_suh et al. we found the songbird germline-restricted chromosome (GRC) can occasionally be inherited from the father

The GRC was previously believed to be only inherited from the mothers, due to its expulsion from sperm. In our study, in addition to our observation of GRC-carrying sperm, we also found a hybrid zebra finch that got his GRC from one of the paternal generations.

Nevertheless, we @fjruizruano @alexander_suh found the GRC and the mtDNA trees from 9 different families do not match. This suggests that in the evolutionary past one GRC might spread the zebra finch population, crossing matriline boundaries via occasional paternal inheritance.

Songbirds have an extra chromosome that was believed to be maternally inherited. A team led by Bart Kempenaers & @alexander_suh shows that it can also be paternally inherited – a key step in understanding the evolution of this chromosome. pnas.org/content/119/4/e2103… @yfpei @PNASnews
