Document Summary

10/13/2014 9:30:00 pm: a turner female also expresses x-linked hemophilia, as does her father. Her mother does not have hemophilia nor is she a carrier for it. Which of her parental gametes was affected by nondisjunction: the mother because the turner female received the x from her father because they both have turner"s syndrome. If the recombination frequency is low then the genes are located. Dna) and recombine it with their own: f-cells, a condition in which the f factor could lose its integrated status, then causing the cell to revert back to its f+ state. When this occurs, the f factor frequently carries several adjacent bacterial genes along with it: f", cells that serve as donors of parts of their chromosomes, f+ cells. If the recombination frequency is high then the genes are located. These strains have a chromosomally integrated f factor that is able to mobilze and transfer part of the chromosome to a recipient f- cell.
