if the allele A frequency is denoted by the symbol p and the allele a frequency denoted by q, then p+q=1. For example, if p=0.7, then q must be 0.3. In other words, if the allele frequency of A equals 70%, the remaining 30% of the alleles must be a, because together they equal 100%. [5]
And since q 1 2 = p 1 r 1, whatever the values of p, q, and r may be, the distribution will in any case continue unchanged after the second generation The principle was thus known as Hardy's law in the English-speaking world until 1943, when Curt Stern pointed out that it had first been formulated independently in 1908 by the German physician ...
Σfxy = 1.g 1 + 0.g 2 + 0.g 3 + 0.g 4 = g 1. Σfx = g 1 + g 2 = p A. Σfy = g 1 + g 2 = p B. The covariance between x and y values is Σfxy - Σfx Σfy = g 1 - p A p B. which is equivalent to the LD coefficient, D, as defined above. It is usually convenient to calculate the correlation rather than the covariance, normalising by the variances:
An allele [1] (or allelomorph) is a variant of the sequence of nucleotides at a particular location, or locus, on a DNA molecule. [2]Alleles can differ at a single position through single nucleotide polymorphisms (SNP), [3] but they can also have insertions and deletions of up to several thousand base pairs.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]

Q2, or the second quarter, refers to the accounting period of April, May and June. Any financial statements you receive from April 1 to June 30 are for Q2 of the fiscal quarter system.
In computational complexity theory, a polynomial-time reduction is a method for solving one problem using another. One shows that if a hypothetical subroutine solving the second problem exists, then the first problem can be solved by transforming or reducing it to inputs for the second problem and calling the subroutine one or more times.
