  2. Dihybrid cross - Wikipedia

    en.wikipedia.org/wiki/Dihybrid_cross

    He applied the same rules of a monohybrid cross to create the dihybrid cross. From these experiments, he determined the phenotypic ratio (9:3:3:1) seen in dihybrid cross for a heterozygous cross. [1] Through these experiments, he was able to determine the basic law of independent assortment and law of dominance.

  3. Test cross - Wikipedia

    en.wikipedia.org/wiki/Test_cross

    This investigation aimed to determinate the inheritance patterns of two characteristics simultaneously and to verify the hypothesis that the inheritance of one trait would remain independent of the other. Termed a dihybrid cross or “two-gene test cross”, this experiment was grounded in the principle of segregation. When conducting a ...

    Figure 1: Inheritance pattern of dominant (red) and recessive (white) phenotypes when each parent (1) is homozygous for either the dominant or recessive trait. All members of the F 1 generation are heterozygous and share the same dominant phenotype (2), while the F 2 generation exhibits a 6:2 ratio of dominant to recessive phenotypes (3).

    The first table lists the company behind the engine, volume and ad support and identifies the nature of the software being used as free software or proprietary software. The second and third table lists internet privacy aspects along with other technical parameters, such as whether the engine provides personalization (alternatively viewed as a ...

  7. Dominance (genetics) - Wikipedia

    en.wikipedia.org/wiki/Dominance_(genetics)

    In dihybrid inheritance we look at the inheritance of two pairs of genes simultaneous. Assuming here that the two pairs of genes are located at non-homologous chromosomes, such that they are not coupled genes (see genetic linkage) but instead inherited independently. Consider now the cross between parents (P-generation) of genotypes homozygote ...

  8. Distributed search engine - Wikipedia

    en.wikipedia.org/wiki/Distributed_search_engine

    The goals of building a distributed search engine include: 1. to create an independent search engine powered by the community; 2. to make the search operation open and transparent by relying on open-source software; 3. to distribute the advertising revenue to node maintainers, which may help create more robust web infrastructure;

  9. Composition over inheritance - Wikipedia

    en.wikipedia.org/wiki/Composition_over_inheritance

    Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.
