Genome assembly landscape of Ossabaw pig genome

(A) Contig N50 of Ossabaw pig and 17 published genomes of other pig breeds. The contig N50 of Ossabaw is much longer than most of (14 out of 17) published pig genomes. This result suggests our sequencing to be effective and economic.

(B) Circos plot of Ossabaw pig and Duroc chromosomes.

(C) Distribution of genome elements of Ossabaw pig. a, photo of the Ossabaw pig 2702 (Donna). b, 19 chromosomes. c, GC content at 100 kb bins. d, gene density at 500 kb bins. e, SNP density at 500 kb bins. f, histogram of DNA transposon ratios. g, histogram of retrotransposon ratios.

(D) Frequency distribution of SNP per 10 kb bin.

(E) Estimated effective population size (Ne) of Ossabaw pig using heterozygous SNPs. LGM: Last Glacial Maximum.
