Only on the first order. Say population is 90% conditioned male (ie, only male children), 5% normal male, and 5% normal female. Only 1 in 19 males mate, while 100% of females mate. Only those females that mated with normal males produce female children. Which means that barring some sort of mutation or drift, the population will eventually go extinct. One possible solution is that a normal male may have a distinctive feature that a percent of females find attractive which could be selected for.
