Info - Test Cross Linkage

Problem Solver

(calculator)

Accepts genotype counts for three genes from a "test cross", and uses the counts to infer:

  • The gametic phase
  • The recombination rate between the three genes
  • The gene order

Test Yourself

(problem generator)

Presents genotype counts observed for three genes from a "test cross". Use these results to propose:

  • Gametic Phase (heterozygote)
  • The gene order
  • Linkage
  • The recombination rate between the three genes
