Haplotypes a group of genes in an organism that is inherited together from a single parent.
Haplogroup is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplogroup is a combination of alleles at different chromosomes regions that are closely linked and that tend to be inherited together.
As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes.
Haplogroups pertain to a single line of descent, usually dating back thousands of years. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual.
