Evolutionary biology Mid‑importance

	Evolutionary biology portal This article is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, and evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

1% critrion?

"In addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic."

The source for this sentence says something entirely different:"A polymorphism is said to occur when the most common allele has a frequency of no greater than 99 percent."

- In other words: Alleles of any frequency, no matter how low, are polymorphisms, as long as the frequency of the respective most common allele is not higher than 99%. RFLP is an example that further illustrates the error of the (former) sentence. --Felix Tritschler (talk) 21:18, 20 September 2021 (UTC)[reply]
