hi
i will help u.,............

There are many meaning of "Chimera " in different context,...........
i will explain u all.............

==========================================

BIOLOGY

In zoology, a chimera is an animal that has two or more different populations of genetically distinct cells that originated in different zygotes; if the different cells emerged from the same zygote, it is called a mosaicism.

Chimeras are formed from four parent cells (two fertilized eggs or early embryos fuse together) or from three parent cells (a fertilized egg is fused with an unfertilized egg or a fertilized egg is fused with an extra sperm). Each population of cells keeps its own character and the resulting animal is a mixture of mis-matched parts. An analogy is two jigsaw puzzles cut using an identical cutter, but with different pictures. A single puzzle can be made out of the mis-matched parts, but the completed puzzle will show parts of both different pictures.

This condition is either acquired through the infusion of allogeneic hematopoietic cells during transplantation or transfusion or it is inherited. In fraternal twins, chimerism occurs by means of blood-vessel anastomoses. The likelihood of a child being a chimera is increased if the child is created via in vitro fertilization. Chimeras can often breed, but the fertility and type of offspring depends on which cell
line gave rise to the ovaries or testes.

=============================================

GENTEICS(medicine)

Chimera is a person composed of two genetically distinct types of cells. Human chimeras were first discovered with the advent of blood typing when it was found that some people had more than one blood type. Most of them proved to be "blood chimeras" -- non-identical twins who shared a blood supply in the uterus. Those who were not twins are thought to have blood cells from a twin that died early in gestation. Twin embryos often share a blood supply in the placenta, allowing blood stem cells to pass from one and settle in the bone marrow of the other. About 8% of non-identical twin pairs are chimeras.

GREEKS

In Greek mythology, the Chimera was an awesome fire-breathing monster with the head of a lion, the body of a goat, and the tail of a serpent. The Chimera was killed by the hero Bellerophon mounted, in most versions of the tale, on Pegasus, the winged horse

In Greek mythology, the Chimera is a monster, depicted as an animal with the head of a lion, the body of a she-goat, and the tail of a dragon (sometimes it has multiple heads). It is a child of Typhon and Echidna. It terrorized Lycia (in Asia Minor), but was eventually killed by the Corinthian hero Bellerophon.

A chimera is an incredible genetic anomaly. You know the two types of twins identical and paternal, a chimera is when the two fertilised eggs merge into one creating a fetus with two different DNA codes. The first time i heard about it was on CSI.

Since you're listing this under Biology, this is probably the meaning you want: "In zoology, a chimera is an animal that has two or more different populations of genetically distinct cells that originated in different zygotes; if the different cells emerged from the same zygote, it is called a mosaicism." - wikipedia

In mythology, it means a fire-breathing monster that was a combo of snake, goat and lion.

It more common usage, it means a scary illusion, like a "boogie man."

This is a creature in Greek mythodology. It was said to be lion, goat and serpant.

Another answer is an animal that has two or more genetically distinct cells.
