On the other hand, standard, or open pollinated varieties are more or less stabilized in their characteristics. They remain fairly consistent, producing seed that will grow into plants more or less like their parent plants, though less uniform than hybrids.
The rank of admiral (or full admiral, or four-star admiral) is the highest rank normally achievable in the U.S. Navy. It ranks above vice admiral (three-star admiral) and below fleet admiral (five-star admiral). There have been 262 four-star admirals in the history of the U.S. Navy. Of these, 221 achieved that rank while on active duty, 40 were promoted upon retirement in recognition of combat citations, and one was promoted posthumously.
David Glasgow Farragut became the first Admiral in the US Navy in 1866. ..... my Version: Farragut was the first 4-star Admiral, and he achieved that rank of simply Admiral, promoting from the 3-star rank of Vice Admiral, on July 25, 1866. However the first specifically admirals in the United States, came about two years prior.
