 | This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |

Dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes. If the one parent homozygous dominant for both genes and the other parent is homozygous recessive for both genes, then the offspring will be uniformly heterozygous for both genes and will display the dominant phenotype for both traits. Self-pollination or crossing of these individuals will result in predictable ratios of both genotype and phenotype in the F2 generation. Deviations from these expected ratios may indicate that the two traits are linked or that one or both traits has a non-Mendelian mode of inheritance.
