The definition "a change in the sequence of DNA within a chromosome that results in a new trait not found in the parent type" is not correct.
- Some mutations have phenotypic consequences, others do not. "...that results in a new trait not found in the parent type" should be removed.
- Mutable genetic material does not exist only in chromosomes. To include the genome of RNA viruses and extrachromosomal material like plasmids, "within a chromosome" should also be removed.
That doesn't leave much behind. I changed it to "any heritable change in the base-pair sequence of genetic material, namely DNA (or RNA in the case of some viruses)". Dr d12 18:42, 20 January 2007 (UTC)
Definition of "Genetic Material"
I have removed infomation about what genetic matterial is and enabled access to infomation on what genetic material is by linking to the definition of genetic material (18.104.22.168 16:31, 28 January 2010 (UTC))
Replacing one 2-letter word with another, "of"
Its one small change but I hope the result of the change is a great reduction of the quantity of ambiguity in the genetics definition. (22.214.171.124 16:39, 28 January 2010 (UTC))
