Genetic mapping experiments performed by Seymour Benzer on rII mutants in the T4 phage showed that the gene is indivisible by the process of mutation and recombination
Indicate whether the statement is true or false
FALSE
Explanation: Benzer's experiments showed that genetic recombination can occur within genes; in other words, that the base pair, rather than the gene, is the unit of mutation and recombination in genomes.
