Question
Differentiate between complete and incomplete linkage.
✓
Answer
| No. | Complete Linkage | Incomplete Linkage |
| 1. | The phenomenon of inheritance of completely linked genes is called complete linkage. | The phenomenon of inheritance of incompletely linked genes is called incomplete linkage. |
| 2. | In complete linkage, the linked genes which are closely located on the chromosome do not separate (no crossing over) and inherit together. | In incomplete linkage, the linked genes which are distantly located on the same chromosome and have chances of separation by crossing over are known as incompletely linked (weakly linked) genes. |
| e.g. | X chromosome of Drosophila males- shows complete linkage. | In Zea mays - colour and shape of grain show incomplete linkage. |
