The chromosome maps are not accurate maps because
(1) Crossing over frequency is higher than recombination frequency
(2) One crossing over interferes and increases the frequency of nearby crossing over
(3) Crossing over frequency decreases towards the ends of chromosome
(4) Heterochromation increases crossing over
