Look up a punnett square. It's pretty simple, man.

An allele is one "piece" of the x shaped chromosome. It occupies a single position on the chromosome, and codes for specific traits.

A genotype is basicly the entire genetic code of an organism.

A phenotype is the physical characteristics of the organism.

An allele is a form of a gene, such as "tall" or "short" that represent the "height" gene.  Every diploid organism has 2 alleles for each gene (except for those on the sex chromosomes).  It is the alleles that determine an organism's genotype.  

The allelic frequency is the number of a particular allele out of the total number of alleles in a population's gene pool.  If there are 50 organisms, there are 100 alleles for height.  If 25 of those are the allele for "short," then the frequency of the "short" allele is 0.25.
