Figure 1From: Multibreed genome wide association can improve precision of mapping causative variants underlying milk production in dairy cattleAssociation analysis of SNP surrounding GHR on BTA20. Associations of SNP in a 30Â Mb region of BTA20 with protein percentage in Holsteins (Black dots), Jerseys (Orange dots) and in a multibreed GWAS (lower panel). The yellow vertical line represents the position of the GHR gene.Back to article page
