2. Monohybrid cross - Wikipedia

   en.wikipedia.org/wiki/Monohybrid_cross

   A monohybrid cross is a cross between two organisms with different variations at one genetic locus of interest. [ 1 ] [ 2 ] The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single location of a gene.

3. Punnett square - Wikipedia

   en.wikipedia.org/wiki/Punnett_square

   The forked-line method (also known as the tree method and the branching system) can also solve dihybrid and multi-hybrid crosses. A problem is converted to a series of monohybrid crosses, and the results are combined in a tree. However, a tree produces the same result as a Punnett square in less time and with more clarity.

4. Millennium Prize Problems - Wikipedia

   en.wikipedia.org/wiki/Millennium_Prize_Problems

   Euler diagram for P, NP, NP-complete, and NP-hard set of problems (excluding the empty language and its complement, which belong to P but are not NP-complete) Main article: P versus NP problem The question is whether or not, for all problems for which an algorithm can verify a given solution quickly (that is, in polynomial time ), an algorithm ...

5. Test cross - Wikipedia

   en.wikipedia.org/wiki/Test_cross

   Monohybrid, also called “single gene test cross”, is used to observe how homozygous offspring express heterozygous genotypes inherited from their parents. The implantation of monohybrid crossing includes signifying the alleles by using characters – recessive allele often is indicated with a lower-case letter, and the dominant allele is ...

6. Lill's method - Wikipedia

   en.wikipedia.org/wiki/Lill's_method

   Finding roots −2, −1 (repeated root), and −1/3 of the quartic 3x 4 +13x 3 +19x 2 +11x+2 using Lill's method. Black segments are labeled with their lengths (coefficients in the equation), while each colored line with initial slope m and the same endpoint corresponds to a real root.

7. Stars and bars (combinatorics) - Wikipedia

   en.wikipedia.org/wiki/Stars_and_bars_(combinatorics)

   The equality ((+)) = (()) can also be understood as an equivalence of different counting problems: the number of k-tuples of non-negative integers whose sum is n equals the number of (n + 1)-tuples of non-negative integers whose sum is k − 1, which follows by interchanging the roles of bars and stars in the diagrams representing configurations.

8. Reciprocal cross - Wikipedia

   en.wikipedia.org/wiki/Reciprocal_cross

   In genetics, a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern. [1] All parent organisms must be true breeding to properly carry out such an experiment. In one cross, a male expressing the trait of interest will be crossed with a female not expressing the trait.

9. Combinatorics - Wikipedia

   en.wikipedia.org/wiki/Combinatorics

   Combinatorics is an area of mathematics primarily concerned with counting, both as a means and as an end to obtaining results, and certain properties of finite structures.It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science.
