|---|---|
| Back | Dihybrid Test Cross (cross a heterozygous individual for two traits with an individual that is recessive for both traits) • If all 4 types of offspring are produced in same proportion, then there is no linkage at all. • If there is some deviation from the ideal 25% ratio, then partial/incomplete linkage is present. • If only parental types are produced (1:1:0:0), then there is complete/tight linkage. |
