Genetics definition
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 (87.80.103.44 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. (87.80.103.44 16:39, 28 January 2010 (UTC))

 * This appears to be real, but is borderline only-in-dictionaries. See:
 * 1984, Virginia Commission of Game and Inland Fisheries, Virginia Wildlife, volume 45:
 * Birdwatchers would enjoy a host of sparrows, a herd of swans, a descent of woodpeckers, a herd of wrens, and mutation of thrushes.
 * 2010, Doug Bennet, Tim Tiner, The Complete Up North: A Guide to Ontario's Wilderness from Black Flies to the Northern Lights, page 57:
 * Names for a group: A flute or mutation of thrushes.
 * 2013, Jason Sacher, A Compendium of Collective Nouns: From an Armory of Aardvarks to a Zeal of Zebras, page 196:
 * A Mutation of Thrushes The authors of the books of venery were not predicting Darwin with this term, but taking a cue from a common fable of the time.
 * The latter source describes a myth of thrushes periodically shedding their legs and growing new ones. bd2412 T 04:24, 30 July 2013 (UTC)


 * If no one objects, I will close this tomorrow as verified. bd2412 T 13:14, 2 August 2013 (UTC)
