Haplotype

A haplotype (from the Greek: ἁπλοῦς, haploûs, "onefold, single, simple") in genetics is a combination of alleles (DNA sequences) at adjacent locations (loci) on the chromosome that are transmitted together. A haplotype may be one locus, several loci, or an entire chromosome depending on the number of recombination events that have occurred between a given set of loci.
