342298 In a dihybrid cross between a true breeding round yellow seeded and true breeding wrinkled green seeded pea plant, the ratio of segregation of round and wrinkled seed traits in \(F_{2}\) is

1 \(9: 1\)

342299 Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the correct answer from the options given below:
Assertion :
Mendel’s law of Independent assortment does not hold good for the genes that are located closely on the same chromosome.
Reason :
Closely located genes assort independently.

1 Both (A) and (R) are correct but (R) is not the correct explanation of (A)
2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of (A)

BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342301 Mendel formulated the laws of heredity considering seven pairs of characters in the pea plant. If he had studied an eighth pair, the law which would have been altered is:

1 Law of independent assortment
2 Law of segregation
3 Law of unit character
4 Law of dominance
