Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason(R).
Assertion (A) : Mendel's law of Independent assortment does not hold good for the genes that are located closely on the same chromosome.
Reason (R): Closely located genes assort independently.
In the light of the above statements, choose the correct answer from the options given below:
Both (A) and (R) are correct but ( R ) is not the correct explanation of (A)
(A) is correct but ( R ) is not correct
(A) is not correct but (R) is correct
Both (A) and (R) are correct and (R) is the correct explanation of (A)
If genes are closely located on the chromosome, they won't assort independently and do not show recombination. Mendel's law of independent assortment holds good only for the genes that are located on the same chromosome, not for the closely related genes. Hence statement 1 is right, and 2nd is incorrect.
very far, therefore, show same arm, therefore no independent assortment
Independent assortment shows independent occur and no chance of
and recombination assortment but the chance of recombination
Occur with high Chances of recombination
percentage. Will be less.
Linkage Linkage Linkage
Recombination Recombination Recombination
Hence, the correct option is (b)
