| Abstract: | In this paper,we Discuss the bisexual branching processes in a genetic context with two mating function that the one is called perfect fid elity mating function and the other has the form L(x,y)=x which means the nu mber of mating units is only ditermined by the number of females.Under these ass umptions,the necessary and sufficient condition of the process extinction with p robability 1 was obtained. |

| Keywords: | Bisexual branching processes Probability of extinction M ating function |
