Benzer's analysis of phage genomes included deletion mapping. Since recombination could not occur in the area of a deletion, an infection by two phage strains, one of which has a deletion and the other a point mutation, that results in no wild-type recombinants being produced indicates ________.
◦ that the deletion includes the position of the point mutation in the same gene
◦ that the deletion includes the position of the point mutation in a different gene
◦ that the point mutation is dominant
◦ that the point mutation is recessive
◦ the distance between the two types of mutation
