Accessions of monoecious
species can also be regenerated through both female and male gametic control (plant to plant hand pollinations and equal number of seeds taken per plant) (Crossa and Vencovsky, 1994).
This effect is quite pronounced in populations with small K and small R, because these are the conditions that insure the greatest deviations of the sex ratio from 1:1, and even with large K and R, the mean time to extinction under monogamy is approximately half that expected for a randomly mating, monoecious

Migalj (1969) found that the acetolyzed pollen grains of dioecious strains tended to have a diameter averaging about 33 pm, while the grains of monoecious
strains were smaller, with a diameter averaging about 27 pm; and the pollen of dioecious plants was also more uniform, while that of monoecious
plants were more variable in size and in number of pores.

There are two categories of plants with imperfect flowers: monoecious
and dioecious plants.
Plants having both staminate and pistillate flowers on the same plant are monoecious
, literally meaning "one house" (see Figure 5-4).
The family is monoecious
and you can see, at this time of year, both male and female flowers on courgettes.
