Wow. This is a complicated question.
A fetus needs two sets of genes. And it would be very awkward if you could get yourself pregnant.
In the end I would just like to say. What does it matter?
Its just how the reproduction system works and it probably won't change much. I wouldn't worry too much.
Fertilization results in a zygote which turns into an embryo, then a fetus, and then a baby -insert animal species here.-
After fertilization, the plant will typically produce berries within a few weeks to months, depending on the species. The process involves the development of the ovary into the fruit, which will then encase the seeds formed from fertilization. The timing can vary based on factors such as plant species, growing conditions, and climate.
The fusing together of two gametes at fertilization is called fertilization or conception. It marks the beginning of the development of a new organism that contains a unique combination of genetic material from both parents.
Because pollination brings pollen grains to the stigma where they germinate to produce a pollen tube and male gametes traveling through this tube reach the embryo sac to perform gametic union with egg nucleus and secondary nucleus to form embryo & endosperm respectively. thus a new generation originates
Reproduction
Internal
Horses are mammals and reproduce internally, and the female gives birth after a gestation period of about 335 to 340 days.
Male and female gametes are brought together during the fertilization process, which results in the formation of a new individual. Depending on the species, this can happen either internally or externally.
Black mambas undergo internal fertilization. Mating occurs in the spring, and after a gestation period, the female lays eggs. This reproductive strategy is typical of many snake species, allowing for a higher chance of survival for the developing embryos.
In some species there is external fertilization. In other species there is live birth. Live birth requires internal fertilization.
The process where sex cells fuse is called fertilization. During fertilization, a sperm cell from a male merges with an egg cell from a female, resulting in the formation of a zygote. This zygote contains a complete set of chromosomes, half from each parent, and begins to divide and develop into an embryo. Fertilization can occur internally or externally, depending on the species.
Depending on the species, fertilization can occur internally or externally. Water aids the fertilization of some organisms because organisms that reproduce externally need water for fertilization to occur.
Pollen from the same species is required for successful fertilization because the pollen grains need to contain matching genetic information to that of the female reproductive structures in the flower. This ensures compatibility and proper development of the embryo. Pollen from different species would not have the necessary genetic instructions for successful fertilization to occur.
That depends on the species you are asking about, mammals fertilize internally and fish externally.
Snails can either fertilize internally or externally, depending on the species. Most terrestrial snails, such as garden snails, engage in internal fertilization, where the male transfers sperm to the female's reproductive tract during mating. In contrast, some aquatic snails may practice external fertilization, releasing eggs and sperm into the water simultaneously for fertilization to occur. This variation in fertilization methods is influenced by their respective environments and reproductive strategies.
true
species have members that share common fertilization mechanisms.
