the female serves much the same function, absorbing, incubating, 'processing' and 'delivering' the 'load' of the male.
consequently, upon 'arrival'; more humans are in evidence after final 'journey' of the 'load'!!
some males could qualify as loadmaster too, but for more short length 'hops'!! and much shorter term load 'management'.
the loadmaster was 'processing' steve's DNA!!
kara favored lapping only, and had no loadmaster inclinations!!
