Question:
Assertion (A): Linked genes do not show dihybrid F2 ratio 9 : 3 : 3 : 1.
Reason (R): Linked genes do not undergo independent assortment.
Assertion (A): Linked genes do not show dihybrid F2 ratio 9 : 3 : 3 : 1.
Reason (R): Linked genes do not undergo independent assortment.
Show Hint
Linked genes:
- Found on the same chromosome.
- Do not assort independently; hence, they deviate from Mendelian ratios.
Updated On: Feb 17, 2025
- Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of the Assertion (A).
- Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
