Talk:Genetic linkage

message: I find it fascinating that geneticists know which human traits are inherited together. I imagine they can predict, for example, the chances that a child who gets his father's hair color will also get some other particular trait from him as well ... and which ones the child will almost certainly get. I sometimes note a physical similarity between a child and one of the parents, and try to see what temperamental or intellectual characteristic they also did or did not get. In so speculating, I'm sort of imagining the kind of genetic map that the experts must have down pat. 
I would think these associations would be all over popular magazines and gossip columns. Why not? Do most people not care? Or aren't they able to grasp what's going on? Anyone care to weigh in on this?  Sfahey 02:49, 6 March 2006 (UTC)

message: Oppose merge Unless this article is preserved as the primary title. "Linkage" is a much more familiar term. It shouldn't be stuck inside an article on Recombination frequency, which fewer people would go to look up. Sfahey 02:58, 9 December 2006 (UTC)

thread_title: Merge from "recombination frequency"

message: Support. I agree, these are duplicate articles. The problem is this: can we use anything from the "linked genes" article here, or should it just be deleted? Dr d12 03:28, 23 January 2007 (UTC)
thread_title: Merge from "Linked genes"

message: The opening paragraph begins:
"Genetic linkage occurs when particular alleles are inherited jointly. Typically, an organism can pass on an allele without regard to which allele was passed on for a different gene."
I would suggest it reads like this:
"Genetic linkage occurs when particular alleles are inherited jointly. Typically, an organism can pass on an allele without regard to which allele was passed on for a different chromosome."
Any comments?

thread_title:  Tooo much redundant information here... 

message: The frequency of recombination should not be confused with the frequency of crossover, since each crossover event produces two recombinant gametes. Also, in the case of double-crossover, two crossover events could produce no recombinant gametes. Therefore, the frequency of crossover is greater than or equal to the frequency of recombination / (over) 2  —Preceding unsigned comment added by 208.81.93.216 (talk) 10:27, 8 October 2009 (UTC)
thread_title:  frequency of crossover 

message: This article has a really good foundation, but (as mentioned above) there's a lot of redundancy and a lot of extraneous information, as well as too few references.  I'm going to start overhauling/reworking the article in hopes to improve it a bit; make clear the history, clarify the definition of genetic linkage, and make some of the prose easier to read/understand.  Any and all help would be appreciated!  Jhfortier (talk) 00:01, 14 February 2010 (UTC)
thread_title: Re-working the article

message: There is the following sentence in the background section: "For example, in fruit flies, the genes affecting eye color and wing length are inherited together because they appear on the same chromosome.". If I understand correctly, it is not enough to have the genes in the same chromosome but it is also needed that they are close enough to each other. Could someone explain whether the sentence is wrong or I miss something? Cheater no1 (talk) 00:58, 14 November 2011 (UTC)
thread_title:  Potentially wrong statement 

message: The following paragraph is highly problematic:
"However, it is important to note that recombination frequency tends to underestimate the distance between two linked genes. This is because as the two genes are located farther apart, the chance of double or even number of crossovers between them also increases. Double or even number of crossovers between the two genes results in them being cosegregated to the same gamete, yielding a parental progeny instead of the expected recombinant progeny."
The reason is that, if two loci are far away from each other, their recombinant frequency will DEFINITELY increase. The frequency is in terms of a large number of offspring, not in terms of a single individual child. 
The problem with the quoted paragraph is it attempts to use an INDIVIDUAL child where two loci far apart link together as a result of even number of crossover among them. It is important to note that in a second, third ... child, you will never be able to guarantee that the number of crossover between the two loci is still EVEN! As a result, as the number of children increases, the two loci would appear uncorrelated, even though some children may exhibit traits of linkage in these two loci.  — Preceding unsigned comment added by Puekai (talk • contribs) 05:59, 30 January 2013 (UTC)
