It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

I[edit]

I suggest that both the founder and bottleneck effects be merged with genetic drift as subtitles. As Jheald suggested, the article "founder population" should become a part of the description of the founder effect (perhaps as part of the effects of a single founder event).-E. D. Sperry 21:51, 24 March 2006 (UTC)

Merge[edit]

Suggest that this page and Founder population should be merged. -- Jheald 12:16, 9 February 2006 (UTC).[reply]

yes it should be merged, it is a good suggestion

Will the search engine register the new page if "founder effect" is typed in? If not, I am not in favor of merging. "Founder effect" should be searchable independently, because this is most likely the phrase that one would encounter in a paper on a different subject.—Preceding unsigned comment added by 71.104.149.120 (talk • contribs)

The Wikipedia search engine is the world's worst. It should be an embarrassment to all of us. However, if the merge went through, we can redirect to the correct page.Ted 01:23, 13 June 2006 (UTC)[reply]

Diagram[edit]

Could we perhaps get an explanation of the diagram? I don't know what the dots are supposed to signify. pogo 06:20, 18 Jun 2005 (UTC)

I second that. -Charlie

Still no explanation, so I've removed the illustration. I tried but I fail to see how it illustrates the founder effect. Piet 10:08, 23 January 2006 (UTC)[reply]

The diagram is still there, and still unexplained. It at least needs some labels (if it is worth keeping). -Michael

The different dot represent different individual with particular alleles. For example squares could have allele B for gene 1 and circles could have allele A for gene 1. Therefore, a founder population consisting of 5 circles will have lost all genetic divergence for gene 1 (they will all have allele A) as opposed to a founder population consisting of 5 squares (they will all have allele B). Guillaume

Founder's Effect[edit]

NB: This has been written as Founder's Effect, which implies the effect was first thought of by somebody called Founder. This is incorrect; rather the founder refers to the founding members of a population 144.32.128.73 25 Feb 2004

To do[edit]

Notable examples of the founder effect in the human population, which should be researched and written about in this article:

Finnish men [1]
Modern-day descendants of Old Testament priests have a remarkably homogeneous distribution of Y chromosomes [2]
In fact, the single nucleotide polymorphism rate in the entire population of 6 billion humans is only what you would expect from a population (at equilibrium) of about 10,000, since the human population has exploded from that kind of number only recently.

ernst mayer didn't invent founder theory[edit]

He used work by Sewall Wright and others that had been describing founder effect since the 30's atleast, he was the first to fully outline how speciation could occur via the founder effect though, in the paper i corrected to 1952. Heres the reference:

http://www.pubmedcentral.nih.gov/picrender.fcgi?artid=1214177&blobtype=pdf

Templeton, A. R. The theory of speciation via the founder theory. Genetics. 94 (4) pp. 1011-38 (1979).

I don't know who invented the term, possibly Wright but thats just an educated guess

sorry i can't be more help and change the whole thing but am very busy at the moment, will be back in a few months when all is good if i remember and the same statements there. —Preceding unsigned comment added by 86.133.219.202 (talk) 02:27, 28 November 2007 (UTC)[reply]

Bad Source[edit]

The article cites a commercial pseudoscience website, http://www.drpeterjdadamo.com/wiki/wiki.pl/Founder_effect. It's currently listed as citation #20. This is not a trustworthy or appropriate source. Bluemonkee (talk) 05:29, 29 October 2012 (UTC)[reply]

Suggested updates[edit]

Not all studies have been initiated after a volcanic eruption. Studies have been conducted when a species is reintroduced to an island where the initial population died off.

Few specific examples of studies are provided, especially in the way of animals and plants.

Whether the founder effect specifically refers to a change in the allele frequencies, or if it refers to a random generation of allele frequencies, which could be identical to the parent population, should be specified. Maloney.138 (talk) 00:30, 30 September 2014 (UTC)[reply]

Filipinos[edit]

How did Filipinos become to be known as founders? They are pretty diverse, as seen with the numerous haplogroups. Compare them to Polynesians or more specifically eastern Polynesians of Hawaii and New Zealand and you will see a huge difference! This is evident as even I am genetically connected, showing up as an autosomal match to someone from Norfolk island, a descendant of Fletcher Christian.

This was added by a IP user on 17 January 2015; plain vandalism, I think. Sophia91 (talk) 23:43, 21 August 2016 (UTC)[reply]

Define first what a founder is[edit]

I know this is too short for an entry. That is why I am not creating it. If somebody could make it into a full article, this would be great: "Founder is the first member of a species to experience a specific mutation that is subsequently passed to its offspring through heredity." ---- Bernburgerin (talk) 07:45, 3 December 2018 (UTC)[reply]

What else happens in genetic drift due to founders effect[edit]

I plan to add a couple sources to support the claim about founder effect studies following the 1883 Krakatoa eruption.Aharveypdx (talk) 08:48, 21 February 2023 (UTC)[reply]

I plan to upload the edits I made to the article in my sandbox. Aharveypdx (talk) 19:32, 17 March 2023 (UTC)[reply]

I made the following edits.

Added equations for calculated increase in homozygosity, loss of heterozygosity, and recessive allele frequencies under General category.

Corrected homozygosity to heterozygosity error under General.

Added image to show loss of heterozygosity.

Fixed equation.

Fixed equations.

Provided attribution for image by Boundless, 2015.

Removed plagiarism from original text "a special case of genetic drift" which is located in the book Conservation and the Genomics of Populations by Allendorf et al.

Added equation for post-bottleneck population growth rate.

Added information about Laysan finch under island ecology. Aharveypdx (talk) 19:34, 17 March 2023 (UTC)[reply]
