Final answer:
The correct scientific name for the garden pea is “Pisum sativum.” It should be capitalized, italicized, or underlined when written.
Step-by-step explanation:
The scientific name for the garden pea is made up of its genus and species in a binomial nomenclature format. The correct way to write this is “Pisum sativum.” In this format, the genus name Pisum is capitalized and the species name sativum is written in lowercase. Both names should be either italicized or underlined, reflecting that this is a scientific name of a species.
Gregor Mendel's research on inheritance was based on pea plants of the species Pisum sativum, which were ideal for genetic studies due to their ability to self-fertilize and produce true-breeding lines, the presence of both male and female reproductive organs in each flower, and distinct phenotypic characteristics.
