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.
Relative genotype frequency and relative allele frequency are the most important measures of genetic variation. Relative genotype frequency is the percentage of individuals in a population that have a specific genotype. gene that can occur in two forms is said to have two alleles. Body color in fruit flies is an example of a gene with two alleles: a dominant allele for brown body color, and a recessive allele for black body color.
