In his book 'Species Plantarum' (1753), Carolus Linnaeus introduced the Binomial Nomenclature system, stating that species may show variations but do not transform into other species. Which of the following is accurate regarding this system?

1. The genus name begins with an uppercase letter, while the species name starts with a lowercase letter.
2. In plant taxonomy (ICBN), tautonyms are not permitted, meaning the genus and species names cannot be identical, such as Mangifera mangifera. However, tautonyms are allowed in zoological taxonomy (ICZN), for example, Naja naja (Indian cobra) and Rattus rattus (rat).
3. The scientific name of mango, following the rules of binomial nomenclature, is correctly written as Mangifera indica Linn.
4. Binomial nomenclature is a standardized method of naming species using two terms, which follow Latin grammar rules but may derive from other languages.

Correct answer: The scientific name of mango, following the rules of binomial nomenclature, is correctly written as Mangifera indica Linn.

Solution

Option C is correct because it correctly follows the rules of binomial nomenclature, where the genus name starts with a capital letter, the species name starts with a lowercase letter, and the author's name (Linn.) is included in abbreviated form.
