Heterosis is a collection of dynamic NFTs by Mat Collishaw that combines genetic algorithms with blockchain technology to create an unprecedented flower hybridisation experience. Each token is a seed with its own genetic code. When two collectors breed their flowers, a new hybrid blossoms — inheriting visible traits and hidden recessive genes from both parents. The concept draws a direct line from 17th-century Dutch Tulip Mania to today’s digital speculation — questioning where beauty is found, and when novelty becomes value.
