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.
When there are two alleles at a locus, the convention is to use p to represent the frequency of one allele and q to represent the frequency of the other. Thus p, the frequency of the CR allele in this population, is 0.8. The frequency of the CW allele, represented by q, is 0.2.
