Which form of reproduction requires two parents?

• A. Asexual reproduction
• B. Sexual reproduction
• C. Binary fission
• D. Budding

Answer: (B)

Two parents are involved in sexual reproduction because offspring come from the genetic material of both individuals. Each parent makes gametes (sperm or pollen, and eggs), which are haploid cells produced by meiosis. When a gamete from one parent fuses with a gamete from the other during fertilization, a diploid zygote forms and develops into an offspring. This fusion also shuffles alleles, creating genetic variation among offspring.

In contrast, asexual forms of reproduction come from a single organism and typically produce genetically similar or identical offspring, without gamete fusion. Examples include binary fission and budding.

So the form that requires two parents is sexual reproduction.
