No, sperm and egg unite to form a zygote, a single fertilized cell. That cell divides again and again, forming a blastocyst. The blastocyst implants in the uterine wall (in placental mammals), where the embryo at last develops. Eventually the embryo grows into a fetus, and the fetus undergoes parturition (it is born).

Does the embryo develops?
The embryo develops not in the wombYour species may vary. Mammalian embryos develop within the uterus of their mothers. Bird and reptile embryos develop inside eggs. Some oviparous embryos develop inside eggs inside their mothers. In some fish and seahorses, the eggs laid by the female, but carried by the males in a pouch and the embryos develop within him.
Where does the embryo develop?
vagina
What is tiny heart-shaped part of a fern that produces both sperm and eggs?
sporophyte
Do clones have identical babies?
No, even if it were possible for 2 cloned females to drop identical eggs at the right time, they would still be fertilised by different sperm. If it was considered possible for cloned males to have identical sperm, those 2 sperm would both have to beat millions of other sperm to get to the cloned eggs.
What would happen to human sperm inside a female dog Does it die immediately or does the sperm try to mate with the females eggs?
The sperm is incompatible with the female eggs, and would not interact with it.
Do embryos have DNA?
Yes. Sperm and eggs carry DNA - this combines to become the DNA of the zygote/embryo.
Why do we get an organism?
We get organisms because eggs and sperm unite to form embryos, usually. Although some organisms form from spores or cell division.
How test tube babies formed?
In short: Several eggs are extracted from the female and sperm is gathered from the male. The eggs are put in a petri dish and the sperm added to that. The resulting embryos are grown in petri dishes until they are either placed in a uterus or frozen for later use.
How do embryos develop externally?
In eggs.
How is internal and external fertilization similar?
-produce a large number of sperm and egg cells -no parental care for developing embryos -The gametes are protected from a harsh enviroment -The gametes are protected from predators
How is a test tube baby done?
When the woman is ovulating doctors retrieve her eggs. They do this by using an ultrasound needle that pierces the vaginal wall to the ovaries, which they can take out remove the eggs. Usually ten to thirty eggs are retrieved. The eggs are then prepared for fertilisation. Meanwhile, semen is being prepared, by being separated from the seminal fluid. Then, the sperm and egg are incubated together in a dish that is designed to hold growing cells. Usually the egg is fertilized after eighteen hours. Or the sperm could be injected directly to the egg. The fertilized egg is left for two days until it has several cells. Embryos are then transferred into the woman. Depending on the age of the woman the number of embryos vary. For older woman about three embryos are placed. The embryos are transferred through the woman's uterus with a thin catheter.

Individual animals that produce both sperm and eggs are called?
Hermaphrodites
What Sex do all human embryos begin with?
the sex of all embryos is decided when the sperm meets the egg. The egg is x and the sperm is either x or y. If y then it is a male and x is female.
