Dihybrid Test Cross Ratio for Completely Linked Genes
When two genes are completely linked, they are located on the same chromosome and are inherited together. Therefore, their alleles will always be inherited in the same combination, resulting in a specific dihybrid test cross ratio.
1. Definition of a Dihybrid Test Cross Ratio
A dihybrid test cross ratio is a ratio of phenotypic outcomes resulting from the mating of a dihybrid individual with a homozygous recessive individual. The purpose of the test cross is to determine the genotype of the dihybrid individual.
2. Calculation of a Dihybrid Test Cross Ratio
The dihybrid test cross ratio is determined by the independent assortment of the two genes. If the two genes are completely linked, they will not assort independently, and the ratio will be different from the expected 9:3:3:1 ratio.
3. Dihybrid Test Cross Ratio for Completely Linked Genes
If two genes are completely linked, their alleles will always be inherited together, resulting in a 1:1 ratio of phenotypic outcomes in the dihybrid test cross. This means that each offspring will have either one of the two possible combinations of alleles, resulting in a 1:1 ratio of phenotypes.
4. Examples of Dihybrid Test Cross Ratios
- If the two genes are unlinked, the dihybrid test cross ratio will be a 9:3:3:1 ratio, which represents the expected phenotypic outcomes resulting from the independent assortment of two genes.
- If the two genes are completely linked, the dihybrid test cross ratio will be a 1:1 ratio, which represents the phenotypic outcomes resulting from the non-independent assortment of two genes.
In conclusion, the dihybrid test cross ratio for two completely linked genes will be a 1:1 ratio, as their alleles will always be inherited together. This ratio is different from the expected 9:3:3:1 ratio resulting from the independent assortment of two genes.
