whether the mode of inheritance is sex-link or autosomal by crossing wild type mother x mutated father

cross wild type with double mutant x double mutant, then self cross the F1

if the ratio is not 9: 3: 3: 1, conduct a test cross: F1 from (2) x double mutant

if the ratio is not 1: 1: 1: 1, calculate recombinant frequency

choose another mutant on the same chromosome to justify the RF.
