=== Mendel's Laws ===
Since Mendel used experimental methods to devise his particulate inheritance theory, he developed three basic laws of inheritance: the [[Law of Segregation]], the [[Law of Independent Assortment]], and the [[Law of Dominance]]:<ref>[http://www.bioedonline.org/slides/slide01.cfm?q=particulate+model+of+inheritance&dpg=2 Ibid.]</ref>
 
==== Law of Segregation ====
Line 28:
 
==== Law of Independent Assortment ====
The alleles of different genes segregate or assort independently of each other during gamete formation. Mendel concluded that different traits are inherited independently of each other, so that there is no relation, for example, between a cat's color and tail length. This is actually only true for genes that are not linked to each other.
 
==== Law of Dominance ====
In the pea plants, Mendel observed that the "T" allele ([[dominant]]) masked the effects of the "t" allele ([[recessive]]). The terms "dominant" and "recessive" are used for the masking and the covered allele, respectively. All offspring from this cross are [[heterozygotes]] in terms of their [[genotypes]]. They also are tall (because the allele for tall masks the allele for short) in terms of their "[[phenotype]]".
