1)Which of the following statements is true regarding thegenetic map distance between two markers?
a) Is inversely related to the frequency of chiasma
b)Is directly related to the frequency of crossing-over.
c)Increases in accuracy as the distance between lociincreases.
d)Can be estimated by multiplying the recombination frequenciesof subinterverals.
e)Adding the subinterverals is less accurate than a direct measureby a two point cross.
2)A recombination map does not directly reflect the physicalmap. Why?
a)Some areas of a chromosome have more crossovers thanothers
b)There is never enough data to be that accurate
c)You always miss double crossovers, but if you found all ofthem the two maps would be identical
d)Any crossover distorts the recombination map
e)None of the above is true. A good recombination map will beexactly what a good physical map will be.
3)Compared to a physical map one can say that a genetic map
