Do you know the correct terms for these definitions?

All of the genes found in a population form the

A group of organisms which are actively or potentially capable of interbreeding to produce fertile offspring.
When there is more than one allele for gene in a population.

Population genetics

You need to to familiar with three areas of population genetics. The Hardy-Weinberg equilibrium predicts the frequencies of the alleles, genotypes and phenotypes that will occur in a population; provided certain conditions are met.

Selection deals with the way the some genotypes confer an advantage on those individuals that process it. These individuals are more likely to reproduce successfully and pass their genes on.

Speciation deals with the way that selection can lead to the evolution of new species.

When you have looked at these three areas there is a multiple choice test on population genetics to try.

p2 + 2pq + q2 = 1

But what does it all mean? There are some good web sites to help you.

1. Go to the University of Virginia site for a basic set of information.

2. Then go to the Hardy-Weinberg tutorial and work your way through the questions.

If you are feeling lazy there is an excel spread sheet to do a quick calculation of the allele and genotype frequencies.
