Resumen en inglés In all living species at most, two parents are needed in order to make an offspring. In this paper, we assume that N parents are needed, and we calculate the optimum N in terms of fitness using a simple probabilistic approach. The probability of finding an attractive partner is set to P. The probability that this partner gives increased fitness is set to 1−R. We show that the best number of partners is N = 2 for any value of R as long as 1/2 <P < 2/3. For P < 1/2, the most beneficial is N = 1 partner. As P increases, there exists an optimum number of partners N > 2
