Assertion : The strength of linkage will be more when the distance between two genes is greater. Reason : Crossing over will be relatively less frequent for distantly located genes.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
D. If both assertion and reason are false.
Step-by-step solution
The strength of linkage will be determined by the distance between two genes. The greater this distance, lower will be the linked strength. Crossing over will be relatively more frequent, if distance between two genes is more.
