The dominant gene is the one that is expressed when alleles are different and only one of the genes is expressed. b. The recessive gene is the one that is masked when alleles ...

Since inheritance of the antibiotic resistance gene cannot occur by homologous recombination, antibiotic-resistant cells must arise by transposition. ...
