What type of reproduction involves two parents?

The correct answer is sexual reproduction, which involves two parents contributing genetic material to produce offspring. In this process, male and female gametes merge during fertilization, creating a new organism with a combination of traits from both parents. This genetic diversity is crucial for the adaptation and evolution of species over time.

In contrast, asexual reproduction involves only one parent and results in offspring that are genetically identical to that parent. Methods like binary fission and cloning are specific forms of asexual reproduction where an organism replicates itself without the combination of genetic material from another organism. Thus, sexual reproduction stands out as it introduces variability and complexity into the genetic makeup of the offspring, which is essential for the health of populations and the survival of species in changing environments.
