What really sets this species apart is how they reproduce. Mourning geckos are all female and reproduce through parthenogenesis, where the mother essentially clones herself to create her offspring. However, their genes have the ability to recombine to allow genetic variation and mutation. Like many other geckos, mourning geckos lay two eggs at a time several times a year. The eggs incubate for 65 to 103 days.

Which one of the following credentials would increase the author's credibility?

  • A. A senior zoologist at a zoo in South America
  • B. The head librarian at a nationally renowned university
  • C. The editor of a prominent American newspaper
  • D. A wildlife photographer for well-known nature periodicals
Correct Answer: A

Rationale: In this context, discussing the reproduction of mourning geckos, a credential related to zoology and animal behavior, such as being a senior zoologist, would enhance the author's credibility. A zoologist specializing in animal behavior and reproduction would have the relevant expertise and knowledge to discuss the unique reproductive characteristics of mourning geckos. Librarians, editors, and wildlife photographers, while respectable professions, do not directly relate to the topic being discussed.
