Who is the father of the ant?

Ants are hatched from eggs laid by queens. The mother of a female ant is a queen ant and her father is a worker ant, while the mother of a male ant is a queen ant and has no father. The reason is that fertilized eggs give birth to female ants, while unfertilized eggs hatch male ants. To put it simply, even the queen ants can lay eggs and hatch small ants without mating, but the hatched ants are all male ants, so the male ants have only female ants and no male ants.
