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.
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 ...
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.
Monohybrid cross between homozygote dominant (GG) and homozygote recessive (gg), always resulting in heterozygote genotype (Gg) and the phenotype associated with the dominant allele, in this case capital G. Monohybrid cross between heterozygotes (Gg), resulting in genptypical ratio 1:2:1 (GG:Gg:gg) and phenotypical ratio 3:1 (G:g).

Mendel found support for this law in his dihybrid cross experiments. In his monohybrid crosses, an idealized 3:1 ratio between dominant and recessive phenotypes resulted. In dihybrid crosses, however, he found a 9:3:3:1 ratios. This shows that each of the two alleles is inherited independently from the other, with a 3:1 phenotypic ratio for each.
