Right, so you have a gene, which is a section of DNA which codes for a specific characteristic, such as hair colour, or eye colour. And an allele is a version of a gene, which would be, for example, for brown hair.

Within a population, whether that's a population of humans or giraffes, the 'gene pool' is basically a way to describe all the genes that are present in one interbreeding population. Humans will have different genes present to giraffes.

The different alleles (versions of genes) in a population. So, for example, if there is some sort of event that kills a lot of organisms (eg an earthquake) the gene pool for that population will probably be reduced because there will be fewer different alleles and only these organisms will reproduce so offspring won't have much genetic variety either and so on (I think this is some sort of genetic bottleneck but I'm not sure so don't worry about it)

Gene pool includes the allele for hair , eye colour and everthing that we can think off right?

Nitpick: there are "alleles" for hair etc, not just one "allele" - most things about the body are not caused by just one allele, but by several in tandem.

Thank you Smaug123 would you mind telling me what is actually short tandem repeat?? is it a section of DNA but it is intron? I find this term quite confusing @@

I'm afraid I'm not a biologist - I have only the haziest idea of what an STR and an intron are :P

A short tandem repeat is basically a set of 2-5 base pairs which just keep repeating themselves...it's a section of DNA, and consists of only introns, so it doesn't code for anything.

Hope that helps
