Talk:Hybrid

I am not sure how to work these two different definitions into the same article. Should it be separated into two articles. Where should go the discussion of hybrid vigor, the Green Revolution, F1 hybrids, F2 hybrids, diploid, triploid, tetraploid, etc.? Rmhermen 14:44, Nov 14, 2003 (UTC)
There is another issue: a hybrid is a cross between two specimen belonging to taxons below the genera level. (This includes crosses with subspecies varieties subvarieties and forms).
There is a second issue: a hybrid of two cultivars. Actually a cultivar is most often a hybrid in its own right. The way cultivars are reproduced is most often under controlled conditions and they can be clones. GerardM
In botany it is accepted to talk about taxons lower than subspecies. So when you have natural varieties, and cross them you get hybrids. This does explain to me why a hybrid can be stronger in botany and not in zoology. Can anyone explain WHY the concept of variety or form is absent in zoology? GerardM
- Wouldn't that be breed for domestic animals at least? Rmhermen 21:50, Dec 11, 2003 (UTC)
- A breed is indeed domestic. As such they are not taxonomically relevant. You do not find a "fresian holstein" for a cow or an "arabian thoroughbred" for a horse when studying the taxonomy of animals. GerardM

Question for the biologists:
Is this line from the 4th paragraph true, strictly speaking? 'To create specialised plants is called cross-fertilisation.' Is that actually the definition of 'cross-fertilisation'?
- English is not my primary language but to me this fourth paragraph is wrong. GerardM 22:01, 23 Jul 2004 (UTC)
Can't you cross-fertilize for another reason? And wouldn't grafting, e.g., be another way of creating a specialized plant? Quill 22:01, 19 Jul 2004 (UTC)
- A graft is special but it is not one organism they are two. The rootstock has properties that make for a more vibrant growth of the graft. A hybrid is one organism. GerardM 21:59, 23 Jul 2004 (UTC)
- Cross-fertilization isn't really the correct term to use here, the sentence as it satands does not convery any information so I'm deleting it and adding a link to plant breeding where hybrids are discussed.--nixie 02:20, 1 Mar 2005 (UTC)
Cypresses
Whilst the example of the cypresses is not untrue, it's not actually very pointful. Plants will readily hybridize with other plants of the same genus. All the other examples are animals, hybrids of which are much more unusual. I'm not sure the single plant example belongs here.

I'm not sure if this anon user's addition should even be kept on this page, but I thought I would at least format it correctly for the time being. [[User:Lachatdelarue|Lachatdelarue (talk)]] 12:53, 19 Sep 2004 (UTC)
- It's a good question, Lach. I like the entry, but since this article is about biology (in the real world), perhaps this is misplaced. So where to put it? Another article, with a link at hybrid (disambiguation)? Quill 23:24, 20 Sep 2004 (UTC)
Wolphin
In the article, it says that a wolphin is a cross between a whale and a dolphin, but that's actually not true. It is a cross between a False Killer Whale and a Bottlenose Dolphin, both of which are dolphins, as the article it links to points out.
