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.
In this scheme, if A and a are alleles for a particular gene locus and each diploid individual has two such loci, then p can be designated as the frequency of the A allele and q as the frequency of the a allele. For example, in a population of 100 individuals in which 40% of the alleles are A, p would be 0.40.The rest of the alleles (60%) would be a and q would be equal to 0.60. p + q = 1.These are referred to as allele frequencies.n this scheme, if A and a are alleles for a particular gene locus and each diploid individual has two such loci, then p can be designated as the frequency of the A allele and q as the frequency of the a allele. For example, in a population of 100 individuals in which 40% of the alleles are A, p would be 0.40.
