  2. Hardy–Weinberg principle - Wikipedia

    en.wikipedia.org/wiki/HardyWeinberg_principle

    The HardyWeinberg principle can also be used to estimate the frequency of carriers of an autosomal recessive condition in a population based on the frequency of suffers. Let us assume an estimated 1 2500 {\displaystyle \textstyle {\frac {1}{2500}}} babies are born with cystic fibrosis , this is about the frequency of homozygous individuals ...

  3. Genotype frequency - Wikipedia

    en.wikipedia.org/wiki/Genotype_frequency

    The HardyWeinberg law describes the relationship between allele and genotype frequencies when a population is not evolving. Let's examine the HardyWeinberg equation using the population of four-o'clock plants that we considered above: if the allele A frequency is denoted by the symbol p and the allele a frequency denoted by q, then p+q=1.

  4. Wahlund effect - Wikipedia

    en.wikipedia.org/wiki/Wahlund_effect

    This point always has a lower heterozygosity (y value) than the corresponding (in allele frequency p) Hardy-Weinberg equilibrium. In population genetics, the Wahlund effect is a reduction of heterozygosity (that is when an organism has two different alleles at a locus) in a population caused by subpopulation structure.

  5. de Finetti diagram - Wikipedia

    en.wikipedia.org/wiki/De_Finetti_diagram

    A de Finetti diagram. The curved line is the expected HardyWeinberg frequency as a function of p.. A de Finetti diagram is a ternary plot used in population genetics.It is named after the Italian statistician Bruno de Finetti (1906–1985) and is used to graph the genotype frequencies of populations, where there are two alleles and the population is diploid.

  6. Additive disequilibrium and z statistic - Wikipedia

    en.wikipedia.org/wiki/Additive_Disequilibrium...

    Similarly, we can also test for Hardy Weinberg Equilibrium using the z-statistic, which uses information from the estimate of additive disequilibrium to determine significance. When using the z- statistic, however, the goal is to transform the statistic in a way such that asymptotically , it has a standard normal distribution .

  7. List of research methods in biology - Wikipedia

    en.wikipedia.org/wiki/List_of_research_methods...

    HardyWeinberg principle: States that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences: Genetics, Evolutionary biology: Hodgkin–Huxley model: Describes how action potentials in neurons are initiated and propagated: Neuroscience: Infinite sites ...

  8. Phenylthiocarbamide - Wikipedia

    en.wikipedia.org/wiki/Phenylthiocarbamide

    By assuming that PTC tasting is determined by a dominant allele at a single autosomal gene, and that the class is an unbiased sample from a population in HardyWeinberg equilibrium, students then estimate allele and genotype frequencies within the larger population. While this interpretation is broadly consistent with numerous studies of this ...

  9. Wilhelm Weinberg - Wikipedia

    en.wikipedia.org/wiki/Wilhelm_Weinberg

    Wilhelm Weinberg (25 December 1862 – 27 November 1937) was a German obstetrician-gynecologist, practicing in Stuttgart, who in a 1908 paper, published in German in Jahresheft des Vereins für vaterländische Naturkunde in Württemberg (The Annals of the Society of National Natural History in Württemberg), expressed the concept that would later come to be known as the HardyWeinberg principle.
