Select the statement that is true.

Sexual reproduction requires a single parent.
Asexual reproduction is a simpler process than sexual reproduction.
Asexual reproduction occurs when two gametes fuse.
Sexual reproduction produces more offspring than asexual reproduction.

Sexual reproduction produces more offspring than asexual reproduction.

The statement that is true is: Asexual reproduction is a simpler process than sexual reproduction.

To determine which statement is true, we need to analyze each statement one by one:

1. "Sexual reproduction requires a single parent" - This statement is incorrect. Sexual reproduction involves the fusion of two specialized cells called gametes, one from each parent, to produce offspring. Therefore, it requires two parents.

2. "Asexual reproduction is a simpler process than sexual reproduction" - This statement is generally true. Asexual reproduction involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. It is a relatively simpler process compared to sexual reproduction, which involves complex reproductive structures and processes.

3. "Asexual reproduction occurs when two gametes fuse" - This statement is incorrect. Asexual reproduction does not involve the fusion of gametes. Instead, it involves the production of offspring from a single parent organism through methods such as budding, fission, or regeneration.

4. "Sexual reproduction produces more offspring than asexual reproduction" - This statement is generally false. Asexual reproduction often produces more offspring than sexual reproduction because it can happen more rapidly, and each parent can produce multiple offspring. Sexual reproduction typically produces fewer offspring since it requires specialized reproductive structures and processes.

Therefore, the correct statement is: "Asexual reproduction is a simpler process than sexual reproduction."
