When conjugation occurs between a Hfr donor and a F⁻ recipient,which of the following describes the outcome
A)F⁺ cells
B)F⁻ cells with some quantity of chromosomal DNA
C)F⁻ cells with no chromosomal DNA
D)F' cells with some duplicate gene pairs

Question

When conjugation occurs between a Hfr donor and a F⁻ recipient, some portion of the donor's chromosomal DNA may be transferred to the recipient, resulting in F⁻ cells with some quantity of chromosomal DNA. However, the recipient does not become a F⁺ cell because the F factor is not fully transferred. F' cells with some duplicate gene pairs would result if there was an error during the recombination process.
