Which of following molecules govern the inheritance of a trait by the offspring?

Correct option is B

The correct answer is:(b) Paternal and maternal DNA
Here's why:
· DNA (Deoxyribonucleic acid) is the molecule that carries the genetic information responsible for the inheritance of traits.
· Inheritance is the process by which genetic information is passed from parents to their offspring.
· Each parent contributes one set of chromosomes to their offspring. Chromosomes are structures within cells that contain DNA.
· Therefore, the offspring receives a combination of genetic material from both parents - their paternal DNA (from the father) and maternal DNA (from the mother).
Thus, the inheritance of traits is a result of the combined genetic contribution from both the paternal and maternal DNA.
