Logical operations comparing numerical constants and/or trait values. when operating on genotypes, the equality and inequality operators require both pairs of alleles to meet the criterion, but the comparison operators test true if either pair of alleles meets the criterion. That is "2/2">"1/3" evaluates to True, but "1/2"=="2/2" evaluates to False.
Example:
>> 1 == 2
=> 0.
>> "1/1"+1 == "2/2"
=> 1.
>> hichol = chol > 5.8
