Fig. 1From: Identification of favorable SNP alleles and candidate genes for traits related to early maturity via GWAS in upland cottonSingle nucleotide polymorphism (SNP) distributions on the 26 chromosomes of upland cotton. At1 ~ At13 and Dt1 ~ Dt13 in vertical axis are the serial number of 26 chromosomes; The horizontal axis shows chromosome length (Mb); 0 ~ 50 depicts SNP density (the number of SNPs per window)Back to article page
