message: I removed the following from "Situtations where punnet squares don't apply"
:*a parent has a disfigured copy of the allele in question.
Does anyone know what this means? Tocharianne 03:25, 17 April 2007 (UTC)

message: Nearly 100% of the recent edits on this article are IP vandalism and the reverting of IP vandalism. Would anyone object to semi-protection?  I know we can keep reverting by hand, but it seems like a waste of effort on an article that remains rather static and is not being actively improved. EdJohnston (talk) 04:39, 8 April 2008 (UTC)
thread_title:  Semi-protection? 

message: There was a brief war of the bots; the project tag was added and removed. I just restored the tag, since we can all agree that this is a topic in Genetics. I also removed some old random stuff at the top of the page. EdJohnston (talk) 03:44, 15 May 2008 (UTC)

message: A Punnett square helps determine the probability of different genotypic outcomes. If a parent is homozygous for a particular allele, it requires only one line. A good example is the Punnett at the top right of this article: there is no need of a second column, which only doubles the number of cells to count.
Maybe the problem comes from the convention of calling it a square. "Grid" might be better, but is more rarely used as a name.
I'd like to see the redundant column removed. As it stands, the diagram seems to be encouraging the unthinking perpetuation of this curious habit of redundancy. Dasyornis (talk) 07:59, 30 June 2010 (UTC)
thread_title:  Redundant rows in Punnett squares 

message: I am a new student to this, but the banana Punnett Square diagram seems incorrectly labeled. The quote says "A Punnett square showing a typical monohybrid cross", yet only one parent is heterozygous while the other parent is homozygous. By definition, a monohybrid cross involves two heterozygous parents. I apologize if I am understanding something incorrectly.

thread_title:  Banana Punnett Square Diagram 

message: When completing a simple Mendelian Punnett square, it is standard convention to not use "X" or "Y" - these letters should be reserved for representing sex chromosomes only - it can be confusing, especially when one goes further into using the Punnett square for sex-linked traits.  Please consider changing the "Y"s to either an "A" or a "B", using the upper case for the dominant trait and the lower case for the recessive trait in the  green and yellow diagram and the explanation.  I have seen this problem in many diagrams where a well-intentioned individual picks "Y" to mean yellow.  For teenagers it can be difficult to explain why it means yellow in one instance and in another it refers to a male.  I am trying to speak out about this because it is a source of confusion.  Additionally, the diagram that uses "B" is essentially correct except the maternal information goes on the left side, and the paternal across the top.  The two-trait Punnett square is simarly flawed to the single trait as the "Y" should not be used there, either.  Thank you for this consideration.

replies: text: Thanks for that! As far as I know paternal does go along the top where there is a preference. I'm not so sure about the "Y"s, but I'll see what I can do about editing the images. I've edited the table to use "a" in the meantime, but others may disagree. sonia♫ 06:21, 14 September 2011 (UTC)

text: For the lead image, I think the Y is okay there since there are some pretty strong redundant cues in the colour. For the other images, those Ys could be confusing. The tables should match the images so we'd want to change both. This image should be SVG, and once it is made into an SVG these changes will be straightforward. I don't know if paternal always goes across the top, conventionally, but that certainly seems common in the textbooks I've seen. Dcoetzee 09:25, 14 September 2011 (UTC)

thread_title:  What is dominant over what? 

message: Am I misunderstanding something or is the punnet square in this section just completely wrong? It seems to be set up as if for an X-linked trait but that isn't what the text describes or what the alleles in the table show.
