प्रश्न
Differentiate between complete and incomplete linkage.
Advertisements
उत्तर
| 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. |
| 3. | Example X chromosome of Drosophila males- shows complete linkage. | Example In Zea mays - colour and shape of grain show incomplete linkage. |

What is crossing over?
Give an example of complete linkage.
Write a note on sex linkage.
When a white eye Drosophila male (Xr Y) is crossed to a red eye female (XR XR), in the F2 generation all the females are red eyed and 50% males are white eyed. In a criss-cross test, when males are white eyed. In a criss-cross test, when a white eyed female (Xr Xr) is crossed to a red eye male (XRY), the F1 generation offspring had white eyed males while the female offspring bad red eyes. Instead of crossing of a white eyed female (Xr Xr} to a red eyed male (XRY), white eye female (XrXr) to white eye male (XrY) is crossed, the F1 generation will have the following phenotypes and genotype.
The genetic map distance between two genes located on the same chromosome can be analyzed by calculating ____________.
After crossing two plants, the progenies are found to be male sterile. This phenomenon is found to be maternally inherited and is due to some genes which are present in ______.
