Question

Assertion (A): Linked genes do not show dihybrid F₂ ratio 9 : 3 : 3 : 1. 
Reason (R): Linked genes do not undergo independent assortment. 
 

• A. Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

Linked genes: - Found on the same chromosome. - Do not assort independently; hence, they deviate from Mendelian ratios.

Answer 1

The Correct Option is A

- Linked genes are inherited together because they are located on the same chromosome. - They do not follow Mendel's law of independent assortment, which is why the dihybrid F\textsubscript{2} ratio 9:3:3:1 is not observed.
