In almost all dioecious species (species with two sexes), the sex ratio is 0.5. There are 1/2 males and 1/2 females. In most species,the Mendelian rules of inheritance explain mechanistically why this is so.

Dioecious - having unisexual reproductive units (flowers, conifer cones, or functionally equivalent structures) occurring on different individuals; from Greek for "two households".
Full article >>>

These cones are unisexual, in fact the plants are dioecious, having separate male and female plants. Cycads were much more prominent in the forsts of the Mesozoic than they are today. Presently, they are restricted to the tropics.
