All that is necessary to hatch a fertilized egg is to keep it at 100-101 degrees for 21 days, turning it several times a day to keep the yolk (soon-to-be-fetus) in the center. A hen does this instinctively. If hatching in an incubator, turn the eggs manually, or use an automatic turner.
Fertilization The process of development begins with the fusion of gametes : egg (ovum) and sperm.The motile sperm swims to the egg, pierces its cell membrane and enters the cell. Fertilization is the fusion of the nuclei of the egg and sperm, and the single cell that results from this fusion is called the fertilized egg or zygote (see Figure 2).
Uterus. The fertilized egg continues to grow developing into a fetus.
when the ovary is fertilized the the fertilized egg will become a zygote
SPOROPHYTE
this process is known as implantation
To the uterus, where it starts to grow.
Fertilization.
It takes place during the menstrual cycle, and the process is called ovulation. (Another name for the fertilized egg is a 'zygote') Ovulation is not a fertilized egg. Ovulation is the release of an unfertilized egg. The fertilized egg implants about 6-8 days after ovulation
A female's fertilized egg spends the majority of time in the uterus. This is where the egg will mature and grow.
In vitro fertilization
A fertilized egg cell is called a zygote. This cell is diploid and it is formed after synapsis during the process of fertilization is complete.
Oviparous animals are known to lay eggs. Some egg laying species are internally fertilized while some are externally fertilized.
In the case of a mammalian egg (humans and so forth), the egg is absorbed into the bloodstream and disappears. If a woman's egg cell is not fertilized, then nothing special happens. The egg cell, the uterine lining, and a certain amount of blood get expelled. Then, usually within 2 weeks, the body prepares the uterus again and releases another egg cell. This process is called the menstrual cycle, or a woman's "period." When an avian egg is not fertilized, the egg will not hatch! An unfertilized egg will not hatch or grow into an animal. After a while, it decomposes. Unfertilized chicken eggs are sold as food.
