Frequency. The frequency of a wave is the number of waves produced by a source each second. It is also the number of waves that pass a certain point each second.The unit of frequency is the hertz (Hz). It is common for kilohertz (kHz), megahertz (MHz) and gigahertz (GHz) to be used when waves have very high frequencies.requency. The frequency of a wave is the number of waves produced by a source each second. It is also the number of waves that pass a certain point each second. The unit of frequency is the hertz (Hz).
A genotype is BB, Bb, or bb. Allele frequencies refers to the frequency of a single allele in a population, while genotype frequency refers to the frequency of the different combination of those alleles in the population.Gamete frequency is equal to the allele frequency since gametes only carry one copy of the genome.llele frequencies are the frequencies of each allele, dominant (A) and recessive (a). In population genetics these are p & q. Gamete frequencies refer to the proportion of gametes made that have each allele.
