Maize and soybean, for example, have one SNP every 104 and 1030 bp respectively (Tenaillon
et al., 2001; Zhu et al., 2003).
Dr Olivier Tenaillon
who led this study commented, "Our study shows that antibiotic resistance can occur even in the absence of antibiotics and that, depending on the type of bacteria, and growth conditions, rather than being costly to maintain can be highly beneficial.
Factors that have previously been shown to produce linkage disequilibrium include non-random mating, familial relationships in the sampled individuals, factors related to the recent demographic history of the population (e.g., bottleneck), and sampling from multiple populations (Slatkin, 2008; Tenaillon
et al., 2008; Wang et al., 2008).
In maize (Zea mays) a SNP is believed to occur every 48 bp and 130 bp in untranslated and coding regions respectively (Tenaillon

For those reasons, LD is expected to be high in this material, and the first experimental results confirm this expectation (Ching et al., 2002; Tenaillon

Despite the extensive use of SNPs to study human genetic disorders, there have been fewer extensive surveys of SNPs in plants (Tenaillon
et al., 2001).
