Global data resource shows genetic diversity of chickens

June 20, 2019

A total of 174 chicken breeds are described in a publicly accessible database which scientists from the University of Göttingen and the Friedrich Loeffler Institute in Neustadt-Mariensee have built up in recent years with numerous international partners. This database, the Synbreed Chicken Diversity Panel (SCDP), includes information about a large proportion of the available chicken species and their diversity. In the accompanying scientific study, the researchers genotyped 3,235 animals for nearly 600,000 single nucleotide polymorphisms (SNPs). SNPs are variations in separate genetic building blocks at specific regions of the genome that vary between individual animals. The researchers created a family tree of exceptional completeness and detail. The results have been published in the journal BMC Genomics.

The variety of breeds in the database ranges from wild birds to commercial broilers and egg-layers. In addition, it includes a range of local breeds from almost every continent as well as strains bred by hobbyists in Germany. In the study, the research team analysed genetic diversity within and between populations. The study showed that genetic diversity is reduced both within the hobby breeds and in high-performing commercial breeds, especially in those bred for egg-laying. In contrast, in African, South American and some Asian and European breeds, there is still considerable genetic diversity. "It is important for the sustainability and flexibility of breeding that these very different breeds are preserved," said Professor Henner Simianer and Professor Steffen Weigend from the Center for Integrated Breeding Research at the University of Göttingen.

The SCDP is a permanent data collection which is constantly being supplemented and expanded. With the publication of this study, all genotype data were uploaded to a data repository and are available to the scientific community for further analysis at https://doi.org/10.6084/m9.figshare.8003909.

These days when we want to know where we are or how to get where we want to go, most of us will pull out a smart phone with a built-in GPS and map app. Some of us old timers might still use an old school paper map from time to time. But we didn't always used to lean so heavily on maps and technology, and in some remote places of the world some people still navigate and wayfind their way without the aid of these tools... and in some cases do better without them.

Dolly Parton's America: Neon Moss
Today on Radiolab, we're bringing you the fourth episode of Jad's special series, Dolly Parton's America. In this episode, Jad goes back up the mountain to visit Dolly's actual Tennessee mountain home, where she tells stories about her first trips out of the holler. Back on the mountaintop, standing under the rain by the Little Pigeon River, the trip triggers memories of Jad's first visit to his father's childhood home, and opens the gateway to dizzying stories of music and migration.
