Answer: 3. Punnett square was developed by a British scientist.

The Punnett square, a tool to show gamete combinations in a cross, was devised by the British geneticist Reginald C. Punnett.

The term 'linkage' was coined by T.H. Morgan, not Stahl. Spliceosomes act in RNA splicing, not translation. Transduction was discovered by Zinder and Lederberg; Altman discovered ribozymes.
