Egg cells are found in the ovaries of a woman. They are released during ovulation and can be fertilized by sperm to potentially form a zygote and develop into an embryo.
Marsupial embryos do not have an amnion. Instead, they develop within a pouch called a marsupium on the mother's abdomen.
Women typically have two embryos when they are pregnant with twins. However, during a normal pregnancy, a woman has one embryo which develops into a fetus.
Yes, an embryo can develop with one X chromosome, rather than the XX or XY chromosome pair. An example of this is girls born with Turner's syndrome, who have only one X chromosome.
Fertilization is the process where a sperm cell fuses with an egg cell to form a zygote. This zygote then starts to divide and develop into an embryo. If fertilization is successful, the embryo implants itself into the uterus where it continues to grow and develop into a fetus.
It probably has to do with the predetermination of the baby's sex. If the father contributed a Y chromosome, then the indifferent gonads would develop into testes. If an X was contributed then they would develop into ovaries.

Bipotential means that the embryo has the potential to develop into either male or female sex organs. At this stage, the primordial gonads are undifferentiated and have the capacity to develop into either testes or ovaries, depending on genetic and hormonal factors.
The sex of an embryo is determined by the presence or absence of a Y chromosome. If the embryo has a Y chromosome, it will develop as male. If no Y chromosome is present, the embryo will develop as female.
The same way that a human embryo or any other mammalian embryo does.
If there was an actual embryo, it was not a false pregnancy.
The embryo develops in the uterus of the mother.
The embryo of a human develops in the uterus of the female body. The uterus provides a protective and nourishing environment for the embryo to grow and develop into a fetus.
in her uterus
The first system to form in a human embryo is the nervous system. The neural tube, which will develop into the brain and spinal cord, is one of the earliest structures to develop in the developing embryo.
In a human female eggs move from the ovaries where they are formed through the Fallopian tubes where they are fertilized if sperm are present to the uterus where they mature into an embryo and later into a fetus and eventually to a child.
