CATSPER haploblocks in the Chinese population in relation to idiopathic asthenospermia-associated single nucleotide polymorphisms (SNPs). HaploView V4.2 was used to define linkage disequilibrium (LD) blocks represented by the triangular lines based on the current genotyping data from the Chinese population. Squares indicate pair-wise r ² values on a red-scale with D′ = 1 (red) through to D′ = 0 (white)
