Sub-index for these pages on genetic mutations and variants

Most pages overlap with each other, so I divided this complex material into manageable chunks!

(2.1) An introduction to genetic variation

(2.2) Changes to the DNA of the genome - what are mutations and variants

(2.3) What causes genetic mutations?

(2.4) Types of mutation deletion, insertion and substitution

(2.5) What are the consequences of mutations?

(2.6) Extra notes on non-coding DNA
