Polymorphism of the exons encoding the pathogen-recognition extracellular domains of Toll-like receptor genes among Stewart Island robin Petroica australis rakiura founders of Ulva Island.

1Numbers in brackets are the number of offspring used to infer the genotypes of the missing 11th (female) and 12th (male) founders. See Methods.2Nucleotide diversity (×104).3These five birds are also the offspring of the 10th founder that could not be genotyped for this locus.4TLR7 primers co-amplified two loci, excludes SNPs that clearly do not follow Mendelian inheritance (likely to be fixed differences). Genotypes could not be inferred.5Length of cloned product (see Results); initial, population-level sequence analyses were based on directly sequenced PCR products (sequence length = 947 bp).
