Why can crossover value never exceed 50%?

thx

The exchange of chromosome segments in a single crossover occurs only between two of the four stands of the paired chromosomes. The other two stands remain intact and move into the daughter nuclei.

Therefore, the recombination or crossover value never exceeds 50%
