During this handshake, the client and server agree on various parameters used to establish the connection's security: 1  The handshake begins when a client connects to a TLS-enabled server requesting a secure connection and the client presents a list of supported cipher suites (ciphers and hash functions).
Allele frequency. Allele frequency is a term of population genetics that is used in characterizing the genetic diversity of a species population, or equivalently the richness of its gene pool.
Allele frequency. Allele frequency, or gene frequency, is the proportion of a particular allele among all allele copies being considered. Formal definition: Allele or gene frequency is the percentage of all alleles at a given locus in a population gene pool represented by a particular allele.t is usually expressed as a percentage. In population genetics, allele frequencies are used to depict the amount of genetic diversity at the individual, population, and species level. It is also the relative proportion of all alleles of a gene that are of a designated type.
