- Many Parents? Torleiv Maseng John F. Moxnes Física, Astronomía y Matemáticas Sex Parent Fitness Evolution Offspring 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 part- ners 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. 2015 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46439436009 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3 Vol.45
