Figure 1: Experimental design and data collected.
From: Genomes and phenomes of a population of outbred rats and its progenitors
The Heterogeneous Stock is descended from eight inbred progenitors through more than 60 generations of outbreeding. As a result, each HS rat chromosome is a fine-grained mosaic of the founder genomes. The outbred rats included in this study were from generations 62 to 70 and were bred at the University of Barcelona (UAB). NIH: National Institute of Health; NU: Northwestern University (see methods). The data collected are shown on the left hand side of the figure, with the number of observation for each indicated in brackets.
