Self-fertilization is really extreme inbreeding. Simply because a plant mates with itself does not imply that progeny must inherit the same genes. The gametes of an individual are not identical, so they can combine in novel ways even in self-fertilization, in this case tending to lead to reduced genetic diversity.
This abstract represents an example in sea anemones. I quote: "However, brooded young of heterozygous individuals were not identical to their parent. but showed 1:2:1 phenotypic segregation ratios consistent with reproduction by self-fertilization." Homozygous individuals would of course be identical in that trait to the parent, since only one particular allele can be inherited. However, heterozygous individuals, upon self-mating, produce the 1:2:1 ratio expected in simple Mendelian inheritance.
The point is that self-fertilization does not necessarily result in identical offspring. Self-fertilization- is a sexual process, not an asexual one, and therefore the progeny are different.- ♦♦♦Vlmastra♦♦♦ ( talk) 02:59, 23 January 2008 (UTC)
If the parent plant is heterozygous at some loci, then the offspring will not all be identical. But, if the parent plant is homozygous (pure-breeding) for all loci, then the progeny will all be identical. Self-fertilization (as a life-style) tends to push breeding lines to fixation of all alleles in the line, at which point the offspring from such plants will all be identical, despite meiosis. As long as there is some outcrossing, this won't happen, but for obligate self-fertilizing plants, sooner or later it will. Though this does not mean that all breeding lines will fix to the same set of alleles, of course. -- EncycloPetey ( talk) 03:25, 23 January 2008 (UTC)

The seed pods of this mustard are LONG - the reference gives 1.5 to 2 inches. I have roughly converted this to metric. -- Dumarest ( talk) 00:45, 22 May 2009 (UTC)
If I remember correctly, the seed likes to remain dormant until scarified. To speed sprouting let the seed sit for several days on moistened tissue in a closed container. When the seed coat is soft, peel or scrape the coat off carefully. Place the now white seed on wet tissue inside a clear container in the light. Be careful not to bake it in hot sun. Wait for the germination inhibitor to photodegrade. Some seed will sprout soon, some later. My Flatley ( talk) 04:03, 1 May 2010 (UTC)
the box at the bottom of the Alliaria petiolata page places the plant in the Alliaceae family, however it's in the Brassicaceae family. —Preceding unsigned comment added by 74.241.13.212 ( talk) 18:50, 7 October 2010 (UTC)
Please improve the article by adding pictures of the low-growing non-flowering first-year form.- 96.237.1.158 ( talk) 20:45, 21 April 2012 (UTC)
I notice that the article is tagged with 'garlic' and has a table of 'Allium' topics, with types of onion and garlic. Since this plant isn't in the onion family, shouldn't that be changed to the mustard family? — Preceding unsigned comment added by 184.147.233.142 ( talk) 23:02, 2 May 2012 (UTC)
Please add photos of the fruit seed-pods.-

It would also be good to have better photos of what the plant typically looks like, first and second year, growing and flowering.-

The common name "skyut" is actually made-up. This is vandalism. Please remove as soon as possible if found again. — Preceding unsigned comment added by 2601:547:A00:ADC4:5D85:5835:6568:B022 ( talk) 19:28, 1 November 2018 (UTC)
As of 7 March 2019, the article claims the plant was introduced because of its vitamin content. No date is given but I think "European settlers" probably arrived before vitamins were a concern. IAmNitpicking ( talk) 21:13, 7 March 2019 (UTC)
Not moved. Consensus is clearly trending against the proposal. bd2412 T 03:19, 20 June 2019 (UTC)
Alliaria petiolata → Garlic mustard – This is absolutely the WP:COMMONNAME. A google news search for "garlic mustard" gives 12,700 results. "alliaria petiolata" gives 307 results. Of the latter articles, every one I checked also used the term "garlic mustard" (usually giving the species name once in parentheses, but using "garlic mustard" elsewhere throughout). Not only is "garlic mustard" more common in journalism, it's more common in the text of the article ( Alliaria petiolata) itself. Alliaria petiolata appears only once (in the first sentence), whereas "garlic mustard" appears 13 times in the article. (It's also used in the title of a related article: Garlic mustard as an invasive species).
"Garlic mustard" also wins in an ngram search.
I will concede that the species name appears slightly more often than the common name in scientific papers, according to Google Scholar: 2,130 results for "alliaria petiolata" since 2015, vs. 1,440 results for "garlic mustard". But it's much less lop-sided than the difference in the News corpus. And the latter corpus is arguably more relevant to judging which name will be more WP:RECOGNIZABLE to "someone familiar with, although not necessarily an expert in, the subject area".

The guiding principle of this guideline is to follow usage in reliable sources. In the vast majority of cases, this will be the current scientific name. This is because the vast majority of plants are of academic interest only to botanists, and botanists almost invariably use scientific names in their published works. On the other hand, when a plant is of interest outside botany—for example because it has agricultural, horticultural or cultural importance—then a vernacular name may be more common.
following usage in reliable sources, just not the majority usage in e.g. newspapers. I'm not (yet) entirely convinced that the species
has agricultural, horticultural or cultural importance, but I'm glad to see that you are now making the case based on the agreed guidelines. Peter coxhead ( talk) 07:41, 7 June 2019 (UTC)
The section on the plant's spread in North America is written in a clearly non-neutral tone, with open criticism of the USDA's Technical Advisory Group and general editorializing in favor of biological control. While these statements may be accurate, they're presented in a clearly unencyclopedic manner. The whole section probably needs some reorganization, anyway - the second and fourth paragraphs state basically the same exact points. Jokullmusic 13:22, 17 August 2019 (UTC)
I don't see why garlic mustard needs two articles. This information should be incorporated into the article here. Ethan Bass ( talk) — Preceding undated comment added 05:20, 29 November 2020 (UTC)
I realize the toxicity statements about 100ppm being toxic to may invertebrates is directly from Cipollini et al 2006, but plenty of other places like Taft 2017 call it "traces of cyanide" and clearly the mechanism for introduction was cultivation by humans as an herb. — Chris Capoccia 💬 13:52, 2 August 2021 (UTC)
