Do genetic mutations change haplogroups?


Do genetic mutations change haplogroups?


A haplotype is a group of alleles that come from one parent. An allele is a different version of a gene that is due to mutation (unintended altering of the DNA that is not in the genetic code). Alleles are on the same part of a chromosome. A haplogroup is a group of haplotypes that share an ancestor with a singe-nucleotide polymorphism (SNP) mutation. Each SNP is a distinct variation in the building block of DNA, or the nucleotide.
