Group by sex

It is easy to investigate the differences between males and females. The sex_predicate() partitions the individuals based on their Sex:

>>> from gpsea.analysis.predicate.genotype import sex_predicate
>>> gt_predicate = sex_predicate()
>>> gt_predicate.group_labels
('FEMALE', 'MALE')

The individuals with UNKNOWN_SEX will be omitted from the analysis.

Note that we implemented this predicate as a genotype predicate. Currently, it is not possible to compare the distribution of genotypes across sexes.
