Mourning geckos (Lepidodactylus lugubris) are truly a unique species. This gecko is small, as it only grows up to 10 cm or 4 inches. With a range of Hawai, the South Pacific islands, and Central and South America these geckos have one of the largest ranges among reptiles. 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 of the following is a conclusion the reader might draw from the Information in the passage?
A. Their small size means mourning geckos are easy to keep as pets.
B. Genetic variation and mutations may give mourning geckos a better chance for survival.
C. Mourning geckos are an endangered species.
D. Because their offspring are clones, all mourning geckos are identical
The passage mentions that mourning geckos reproduce through parthenogenesis, but their genes have the ability to recombine, allowing for genetic variation and mutation. This genetic variation could potentially enhance their chances for survival in changing environments.
Therefore, the Correct Answer is B.
