Data from: Altruism or selfishness: Floral behavior based on genetic relatedness with neighboring plants

Kin recognition in plants may lead to plastic changes in their behavior,
such as altering their floral display size. In this study, we conducted
evolutionary simulations of the two floral tactics utilized by plants
depending on the genetic relatedness of their neighboring plants. We found
that the evolutionary consequences of floral display size in plants can be
classified into four types, which were determined by pollinator foraging
behavior and plant ecological traits. The plants that grew with kin
behaved altruistically by increasing their floral display size, while
those that coexisted with strangers behaved selfishly by reducing their
floral display size. Moreover, our findings suggest that kin recognition
also increases intraspecific variation in floral display size and seed
production and decreases the genetic diversity of plant populations.
