Genetics

a species can gradually change into new species

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 method an organism uses to produce offspring

the way that a species creates offspring

Finches developed many different adaptations. For example, one type of finch had a short strong beak meant for cracking seeds, while another had a long narrow beak for gathering food from the inside of flowers, and cacti, therefore making each species more adapted to its specific environment and more able to gather food then they would on another island with a different main food source.
