What is the difference between a haplotype and a genotype?
These are two closely related ideas. A haplotype is a set of DNA variations that are usually inherited together. These sets or haplotypes are located on one chromosome. The alleles making up a haplotype can be located in different places on the chromosome but they are inherited together.
The genotype can refer to a single trait or multiple traits inherited together from a parent. The genotype is the combination of genes at a particular locus.
Thus, the genetic material in a haplotype can be at different loci or positions on the chromosome but for a genotype the genetic material is all at one locus.
