Model Answer
(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
A mango seed inherits genetic material from parent plant, and heredity ensures traits are reliably passed to offspring, so it germinates into a mango tree only.
Source: Chapter 8, Section 8.2 (Heredity)
Explanation
- The assertion is true: a mango seed carries the genetic blueprint of the mango plant and will always grow into a mango tree.
- The reason is also true and directly explains the assertion: heredity (rules of inheritance) ensures that offspring reliably resemble their parents.
- Since R correctly explains why A is true, option (A) is the right choice.
- Key line from textbook: "The rules of heredity determine the process by which traits and characteristics are reliably inherited."
