  2. Genotype frequency - Wikipedia

    en.wikipedia.org/wiki/Genotype_frequency

    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]

  3. Hardy–Weinberg principle - Wikipedia

    en.wikipedia.org/wiki/Hardy–Weinberg_principle

    There is 1 degree of freedom (degrees of freedom for test for Hardy–Weinberg proportions are # genotypes − # alleles). The 5% significance level for 1 degree of freedom is 3.84, and since the χ 2 value is less than this, the null hypothesis that the population is in Hardy–Weinberg frequencies is not rejected.

  4. Linkage disequilibrium - Wikipedia

    en.wikipedia.org/wiki/Linkage_disequilibrium

    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:

  5. Polynomial-time reduction - Wikipedia

    en.wikipedia.org/wiki/Polynomial-time_reduction

    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.

    Therefore, the graph of the function f(x − h) = (x − h) 2 is a parabola shifted to the right by h whose vertex is at (h, 0), as shown in the top figure. In contrast, the graph of the function f(x) + k = x 2 + k is a parabola shifted upward by k whose vertex is at (0, k), as shown in the center figure.

    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.

  8. Rational root theorem - Wikipedia

    en.wikipedia.org/wiki/Rational_root_theorem

    Moreover, if one sets x = 1 + t, one gets without computation that () = (+) is a polynomial in t with the same first coefficient 3 and constant term 1. [2] The rational root theorem implies thus that a rational root of Q must belong to { ± 1 , ± 1 3 } , {\textstyle \{\pm 1,\pm {\frac {1}{3}}\},} and thus that the rational roots of P satisfy x ...

  9. Fanconi anemia - Wikipedia

    en.wikipedia.org/wiki/Fanconi_anemia

    Fanconi anemia (FA) is a rare, autosomal recessive, genetic disease resulting in impaired response to DNA damage in the FA/BRCA pathway. Although it is a very rare disorder, study of this and other bone marrow failure syndromes has improved scientific understanding of the mechanisms of normal bone marrow function and development of cancer.
