Question

Why are offspring from sexual reproduction genetically unique?
Options
A Due to mitosis
B Because of random fusion of gametes and recombination
Correct Answer
C Because of identical DNA sequences
D Due to binary fission
Correct Answer

Option B is the correct answer.

Detailed Explanation

Genetic uniqueness arises from three key events in sexual reproduction: independent assortment and crossing over during meiosis (creating diverse gametes), and the random fusion of any sperm with any egg during fertilization.

Hint

Uniqueness comes from shuffling genes twice—during gamete formation and during pairing.
