Since the chromosomes of F- and Hfr bacteria differ in the type of their genetic linkage (Jacoh & Wollman, 1958) and in the manner of their duplication (Nagata, . 1962), two strains of E. coli were used, B3 (F-) (Brenner) and K12 3000 thy- B 1 - (Hfr).

Genealogical DNA test
A genealogical DNA test looks at a person's genome at specific locations. Results give information about genealogy or personal ancestry. In general, these tests compare the results of an individual to others from the same lineage or to current and historic ethnic groups. The test results are not meant for medical use, where different types of genetic testing are needed. They do not determine specific genetic diseases or disorders (see possible exceptions in Medical information below). They are intended only to give genealogical information.
