Question
Please explain thoroughly with concepts and diagrams.
I attempted by only utilizing the AB/aa recombinant which is aB and the value is 0.1, for the same parental I used dE parental of 0.45. Obtaining a value of progeny of 45. However, I am not confident in my answer, because I am not using the right side ab/ab de/de. Please explain the question.
Thank you
