-In Table 8.1,if culture 1 mutates to Hfr,what will be the result of conjugation between the two cultures?
A)They will both remain the same.
B)1 will become F⁺,leu⁺,his⁺; 2 will become F⁺,leu⁺,his⁺
C)1 will remain the same; recombination may occur in 2
D)1 will become F⁻,leu⁺,his⁺; 2 will become Hfr,leu+,his+
E)The answer cannot be determined based on the information provided.

Culture 1 mutating to Hfr (High frequency of recombination) means it can transfer parts of its chromosome to Culture 2 during conjugation. Culture 1 remains the same because it is the donor, and Culture 2 may incorporate the leu+ and his+ genes through recombination, potentially changing its phenotype.
