One way is through a competition - based story. For example, a group of farmers bet on which male and female livestock will breed the most valuable offspring. The sex of the animals is a crucial factor as different sexes may have different genetic advantages. This can create a plot full of anticipation and drama as the farmers wait to see the results of the breeding.
A story could also present breeding, bet and sex in a historical context. In ancient civilizations, there were often beliefs and practices related to breeding and the importance of the sex of offspring. A story could be about a bet made by two nobles in an ancient society regarding the breeding of horses. The sex of the foal was highly prized, and different sexes were associated with different levels of status and wealth. The story could explore how this bet affected the relationships between the characters and the society as a whole.
