### What is the allele frequency?

Allele frequency is the frequency (proportion) of alleles in a
population. It can be expressed as a percentage or a decimal.
For example, suppose a population has 10 individuals and there
are two alleles (A and a) of a gene. Suppose the individuals are as
follows:
4 AA individuals = 8 A alleles
4 Aa individuals = 4 A alleles and 4 a alleles
2 aa individuals = 4 a alleles
So there are (8 + 4) = 12 A alleles in the population and (4 +
4) = 8 a alleles in the population.
The frequency of A alleles is therefore 12/20 = 0.6 or 60%.
The frequency of a alleles is 8/20 = 0.4 or 40%.
(Notice that the total number of alleles equals 1.0 or
100%.)

### The first class in a relative frequency table is 50-59 and the corresponding relative frequency is 0.2What does the 0.2 value indicate?

The sum of the relative frequencies must equal 1 (or 100%),
because each individual relative frequency is a fraction of the
total frequency. The relative frequency of any category is the
proportion or percentage of the data values that fall in that
category.
Relative frequency = relative in category/ total frequency
It means a number in that class appeared 20% of the total
appearances of all classes

### What is relative frequency?

Relative frequency is the proportion of all given values in an
interval, i.e., the frequency of the event/value divided by the
total number of data points.
In other words...
If you picked 12 marbles out of a bag, and 9 of them were green,
the frequency of green marbles would be 9... but the relative
frequency would be that number (the frequency) divided by the
total number of marbles... so the relative frequency would be 9/12
or 3/4.
--
Relative frequency is the time that you get something
successfully over the total number of times attempted... for
example.. you flipped a coin 10 times, and you got heads 4 times.
the relative frequency would be 4 over 10.
