Web4.2 Haplotype. A haplotype is a collection of genes inherited from a single parent [35 ]. The term haplotype is derived from the word “haploid”, which is having a single copy of each chromosome [ 36 ]. A haplotype containing only one set of chromosomes is the main difference between a haplotype and a genotype. WebGenotype data are given for three samples, two of which are phased and the third unphased, with per sample genotype quality, depth and haplotype qualities (the latter only for the phased samples) given as well as the genotypes.
