The subtle differences at loci shared by all organisms can discriminate at the species level
– e.g. 16S rRNA or cytochrome C sequences
– sequence polymorphisms
hypervariable repeated sequences are only shared by some individuals combinations give individual discrimination
– VNTR & STR length polymorphisms
Some genes encode single gene traits such as variants cause disease e.g. cystic fibrosis, huntingdon’s
other phenotypes are extremely complex genetically - though heritability is still seen schizophrenia, heart disease
