  2. Punnett square - Wikipedia

    en.wikipedia.org/wiki/Punnett_square

    In this example, both parents have the genotype Bb. For the example of eye color, this would mean they both have brown eyes. They can produce gametes that contain either the B or the b allele. (It is conventional in genetics to use capital letters to indicate dominant alleles and lower-case letters to indicate recessive alleles.)

  3. Directional selection - Wikipedia

    en.wikipedia.org/wiki/Directional_selection

    Three different types of genetic selection. On each graph, the x-axis variable is the type of phenotypic trait and the y-axis variable is the amount of organisms. Group A is the original population and Group B is the population after selection. Top (Graph 1) represents directional selection with one extreme favored.

  4. Dihybrid cross - Wikipedia

    en.wikipedia.org/wiki/Dihybrid_cross

    In these squares, the dominant traits are uppercase, and the recessive traits of the same characteristic is lowercase. In the following case the example of pea plant seed is chosen. The two characteristics being compared are; Shape: round or wrinkled (Round (R) is dominant) Color: yellow or green (Yellow (Y) is dominant)

  5. Dominating set - Wikipedia

    en.wikipedia.org/wiki/Dominating_set

    There are graph families in which γ(G) = i(G), that is, every minimum maximal independent set is a minimum dominating set. For example, γ(G) = i(G) if G is a claw-free graph. [6] A graph G is called a domination-perfect graph if γ(H) = i(H) in every induced subgraph H of G. Since an induced subgraph of a claw-free graph is claw-free, it ...

  6. Disruptive selection - Wikipedia

    en.wikipedia.org/wiki/Disruptive_selection

    These charts depict the different types of genetic selection. On each graph, the x-axis variable is the type of phenotypic trait and the y-axis variable is the amount of organisms. Group A is the original population and Group B is the population after selection. Graph 1 shows directional selection, in which a single extreme phenotype is favored.

  7. Dominance (genetics) - Wikipedia

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

    Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.

  8. Dominator (graph theory) - Wikipedia

    en.wikipedia.org/wiki/Dominator_(graph_theory)

    The dominance frontier of a node d is the set of all nodes n i such that d dominates an immediate predecessor of n i, but d does not strictly dominate n i. It is the set of nodes where d 's dominance stops. A dominator tree is a tree where each node's children are those nodes it immediately dominates. The start node is the root of the tree.

  9. Competitive exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Competitive_exclusion...

    The best-known example is the so-called "paradox of the plankton". [6] All plankton species live on a very limited number of resources, primarily solar energy and minerals dissolved in the water. According to the competitive exclusion principle, only a small number of plankton species should be able to coexist on these resources.
