Topic 10.3 = Gene Pool And Speciation
Allele Frequency:
Allele frequency is the proportion of
all copies of a gene that is made up
of a particular gene variant (allele)
Gene Pool:
The total collection of different
alleles in an interbreeding
population
Example:
If a recessive allele (h) made up 2% of the total in a human population, then the
dominant allele (H) would make up 98%.
The frequency for h would be expressed as 0.02, and for H 0.98
REMEMBER: (Recessive allele frequency) + (dominant allele frequency) = 1
New allele combinations lead to new phenotypes that can then be selected for, or
against by the environment. This leads to evolutionary change in species

The reproductive isolation only promotes selection in sexually reproducing organisms; it
does not apply to single celled organisms.
