- Located on a specific position on one type of chromosome
- Located on a specific position on one type of chromosome
- Allele
- The various specific forms of a gene
- Alleles differ from each other by one or a few bases only
- Mutations
- Random changes in allele formation- there is no mechanism for a particular mutation being carried out
- Sickly-Cell Anemia
- Causes from base substitution mutation as well as a change to the base sequence of mRNA transcribed from it
and a change to the sequence of a polypeptide in hemoglobin
