Directions: In the following questions, a statement of assertion (A) ...
Assertion: Changes in non-reproductive tissues can be passed on the DNA of the germ cells.
Reason: Inherited traits include the traits developed during the lifetime of an individual that cannot be passed on to its progeny.
The correct answer is option 'D' - Assertion (A) is false but reason (R) is true.
Explanation:
- The assertion states that changes in non-reproductive tissues can be passed on to the DNA of the germ cells. This means that any changes or modifications that occur in non-reproductive tissues, such as muscles or skin, can be inherited by the offspring.
- However, the reason states that inherited traits do not include the traits developed during the lifetime of an individual that cannot be passed on to its progeny. This means that the traits acquired or developed by an individual during its lifetime, also known as acquired traits or acquired characteristics, are not passed on to the offspring through DNA. These traits are not heritable and cannot be inherited by the next generation.
- The reason is true because acquired traits are not passed on through DNA. For example, if a person develops strong muscles through exercise, their offspring will not automatically inherit those strong muscles.
- On the other hand, changes or modifications that occur in reproductive tissues, such as the sperm and egg cells, can be passed on to the offspring through DNA. These changes can be the result of mutations or variations in the DNA sequence.
- Therefore, the assertion is false because changes in non-reproductive tissues cannot be passed on to the DNA of the germ cells, which are responsible for transmitting genetic information to the next generation.
- It is important to note that while acquired traits cannot be inherited, they can still influence the phenotype or physical characteristics of an individual during their lifetime.
