Suppose the map for a particular human chromosome interval is: a--1 mu--b--1 mu--c--1 mu--d--1 mu--e--1 mu--f
In a man heterozygous for all six genes, what fraction of his sperm would be recombinant in the a-f interval?
A)0%
B)1%
C)2.5%
D)5%
E)Cannot be determined

The total map distance from a to f is 5 map units (1 mu each between adjacent genes). The fraction of recombinant gametes is equal to the map distance, so 5% of the sperm would be recombinant in the a-f interval.
