Q. One map unit of one centimorgan corresponds to recombination frequency of:

A) 0.1%
B) 1%
C) 10%
D) 9.88%

... Answer is B). 1%

One genetic map unit (m.u.) is defined as that distance between genes for which one product of meiosis out of 100 is recombinant. Put another way, a recombinant frequency of 1 percent is defined as 1 m.u., and an RF of 6 percent is defined as 6 m.u., and so on. A map unit is sometimes referred to as a centimorgan (CM) in honor of Thomas Hunt Morgan, a pioneer in the field of chromosome mapping.
