Study the following statements.
(A). Due to incomplete linkage the parental traits are inherited in offsprings.
(B). Due to incomplete linkage new traits occur in offsprings.
(C). X-chromosome of Drosophila males show complete linkage
(D). In Zea mays- color and shape of grain show complete linkage
Choose the correct answer from the options given below:
(A). Due to incomplete linkage the parental traits are inherited in offsprings.
(B). Due to incomplete linkage new traits occur in offsprings.
(C). X-chromosome of Drosophila males show complete linkage
(D). In Zea mays- color and shape of grain show complete linkage
Choose the correct answer from the options given below:
Options
- AStatements (A) and (C) are correct
- BStatements (A) and (D) are correct.
- CStatements (B) and (D) are incorrect.
- DStatements (A) and (D) are incorrect.
Correct answer
D. Statements (A) and (D) are incorrect.
Step-by-step solution
Statement (A) is incorrect because parental traits are inherited due to complete linkage. Incomplete linkage leads to the formation of recombinant or new traits along with parental traits, but the inheritance of parental traits itself is a feature of linkage, not specifically incomplete linkage.
Statement (B) is correct because incomplete linkage involves crossing over, which produces new trait combinations (recombinants) in the offspring.
Statement (C) is correct because male Drosophila exhibits complete linkage (no crossing over occurs in male Drosophila).
Statement (D) is incorrect because in Zea mays, the genes for the color and shape of the grain exhibit incomplete linkage, not complete linkage.
Therefore, statements (A) and (D) are incorrect.
Answer: Statements (A) and (D) are incorrect.
Statement (B) is correct because incomplete linkage involves crossing over, which produces new trait combinations (recombinants) in the offspring.
Statement (C) is correct because male Drosophila exhibits complete linkage (no crossing over occurs in male Drosophila).
Statement (D) is incorrect because in Zea mays, the genes for the color and shape of the grain exhibit incomplete linkage, not complete linkage.
Therefore, statements (A) and (D) are incorrect.
Answer: Statements (A) and (D) are incorrect.
