Frequencies

Frequency

1. (Science: physics) The number of occurrences of a periodic or recurrent process per unit time, for example the number of vibrations of a particle per second or the number of repetitions of a complete wave form (cycles) per second.

2. (Science: statistics) The number of members of a population or statistical sample falling in a particular class.

3. Relative frequency, the average number of occurrences of a particular event in a large number of repeated trials.

Re: Re:

Unless you're suggesting that some "races" have better genetics than others. Allele frequencies vary between poopulations. The question is not whether there's a difference (in genetic IQ predisposition), but how large that difference is. I think the adoption ...

Microevolution verus Macroevolution

Evolution is defined as variation in the frequencies of alleles, where an allele is a specific iteration of a given gene. Microevolution is defined as variations in the frequencies of alleles below species level, in a population of organisms. ...

Electromagnetic fields generated by the human body

I read this thread with interest. I'm surprised there is no mention of Leon Trotsky's work. For example his work with low frequencies and how the US military, some believe have used to develop weapons based on this. Search for trotskey on youtube and look for a 45 minute or greater ...

ecological genomics: Microsallites & allele frequency

... studies have looked at genotypic diversity (i.e. the number of alleles) vs environmental variable. But I was wondering if anybody has looked at frequencies of individual alleles and if that has any functional implication. Any comments would be appreciated! msats_correlated_with_SST.png
