The male cones are located below the female cones on a tree. Also, the timing of cone production varies among trees to ensure that one tree will be producing male cones while another tree produces female cones. This is a form of temporal regulation.
Mendel removed the reproductive organs (anthers) of the plants to prevent self-fertilization and control the breeding process, ensuring that he could control which plants were cross-fertilized.
Conifers have pollen grains that are dispersed by wind, allowing them to reproduce without relying on water for fertilization. This adaptation allows conifers to thrive in a variety of environments, including those with limited access to water.
monohybrid cross
welll because one is a producation but the other one isn't and the growth and how it grow at the botom of all top so it is werid Self-fertilization and cross-fertilization are the same as asexual and sexual reproduction. Self-fertilization uses itself to fertilize, which cross-fertilization takes from another plant to make a new generation of the plant.
The different types of sexual reproduction in organisms include internal fertilization, external fertilization, and self-fertilization.
After fertilization in conifers, the zygote develops into an embryo within the seed. The seed matures and is eventually released from the cone. It may then germinate and grow into a new tree under favorable conditions.
Self-fertilization is theoretically possible in the Gumamila flower, which belongs to the Hibiscus genus. However, many species of Hibiscus are primarily outcrossing, meaning they depend on pollen from a different plant for fertilization. Some species have mechanisms to prevent self-fertilization to promote genetic diversity and reduce inbreeding.

Because conifers are pollinated by wind hence to ensure fertilization of each egg clouds of pollen grains are formed.
The agents of pollination for conifers are usually wind and rarely insects. Conifers produce pollen in large quantities that is lightweight and easily carried by the wind to reach female cones for fertilization. The lack of showy flowers and nectar means that conifers do not rely on insects for pollination as much as other plants do.
Gregor Mendel prevented self-fertilization in his pea plants by removing the stamens (male reproductive organs) from the flowers before they matured, thus preventing the plants from self-pollinating. This allowed him to control the pollination process and ensure that only desired crosses were made between different plants.
well by pollens truth/ When both male & female gametes are compatible to mate, self-pollination results in self fertilization.
Conifers are typically pollinated by wind, as they produce large amounts of lightweight pollen that is carried by the wind to reach female cones for fertilization. Some conifers, like pines and spruces, have separate male and female cones to facilitate this process. Insects are generally not involved in the pollination of conifers.

Becuase when they self fertilize they cannot get the proper amount of sunlight, but when they dont self fertilize they can get the proper amount of sunlight
A limit to the possibilities for diversity is the disadvantage of self fertilization of flowers. Self fertilization draws upon the particular flower's gene base and nothing else or more. It's with other forms of fertilization such as cross and manual pollination whereby other characteristics such as color and disease resistance may be introduced.
