Someone needs to disambiguate this. KirbyMeister 01:36, 10 May 2004 (UTC)
The Idea of crossing over was first proposed by F.A. Janssens. Does anybody know anything more about him? Fawcett5 18:17, 17 January 2006 (UTC)
Yes, that needs to be changed. The cytological basis of crossing over (and even the term "crossing-over") was first described by F.A. Janssens. TH Morgan just used that knowledge to help him expain gene linkage. Morgan postulated that the crossing over (that Janssens had already discovered) created new chromosomal types in a few gametes.
This article should probably be merged with / redirect to genetic recombination. Gringer 03:02, 7 July 2006 (UTC)
- Sorry, after reading Genetic recombination, it makes sense to keep this. The pictures, at least, should be changed to reflect the breakage and rejoining mentioned in the first paragraph, rather than physical twisting of chromosomes. --Gringer 03:12, 7 July 2006 (UTC)
[edit] significance of crossing over
what is its significance can naybody tell me please —The preceding unsigned comment was added by 203.101.182.58 (talk) 11:28, 27 February 2007 (UTC).
