genetic distance

genetic distance

  1. (in genetic mapping) the distance (in map units) between loci on a GENETIC MAP.
  2. (in TAXONOMY) a measure of the relatedness between, for example, any pair of populations on the basis of ALLELE FREQUENCIES, DNA sequences or phenotypic traits.

In order to discover a region suitable for genetic distance analyses and population diagnostic single nucleotide polymorphisms (SNPs), we isolated regions of the alignment to produce a 48-bp fragment of COI that minimized missing data while optimizing taxonomic coverage.
