An amniocentesis, or Amniotic fluid test (AFT) is used to detect chromosomal abnormalities. A very safe, commonly used test, capable of generating a great deal of information.

What is the superclass of mammalia?
Mammalia fall within the amniota, as do reptilia which in turn include turtles, lizrds, crocodiles and birds. Amniotaare a subclass of tetrapoda, having an egg with an amnios or pouch within which an embryo develops.
What is an important characteristic of the eggshell of a reptile?
Reptile eggs are defined by having an amnios. Amphibian eggs must be deposited with water. This evolutionary development allowed reptiles to more effectively dominate the terrestrial world since their eggs would be able to survive the arid land.
How does anatomy and circulation differ among amniotes?
Amniotes differ from earlier vertebrates in that they can complete their life cycle on land rather than in water. Earlier vertebrates had to have water to lay eggs at the minimum. Amniotes developed eggs with amnios which allowed the eggs to be laid on land or carried by the mother.
Up to when can you have an amniocentesis?
Amniocentesis can be done no earlier than the fourteenth week of pregnancy. Sufficient amniotic fluid has to be present to do an amniocentesis. Amnios can be done well after 15 weeks but you shouldn't have one before then.
Do chimpanzee have amniotic egg?
An amniotic egg is an egg which contains an amnios, a fluid filled membrane that surrounds the embryo to protect it. All reptiles, birds, and mammals produce amniotic eggs during reproduction. Those that give birth to live young, including mammals such as chimpanzees, develop an amniotic egg, although it doesn't have a shell, and retain the egg within the body until the offspring is born.
What is an Archenteron in the cleavage stage of an human embryo?
Gastrulation in the human embryo coincides with the formation of the primitive streak on the epiblast and the horizontal growth of both epiblast and hypoblast. In the human embryo, there is no archenteron. Its closest equivalent may be the formation of the primitive streak, where the primitive streak is the equivalent of the blastopore in smaller organisms such as the frog or the zebrafish. The formation of the primitive streak is characterised by 1) the transformation of the hypoblast into the endoderm: the growth of epiblast cells toward the inside, replacing (a combination of cell migration and differentiation) hypoblast cells with endodermal cells, 2) the creation of the mesoderm: the growth/migration/differentiation of epiblast cells toward the middle, in between the epiblast/ectoderm and the endoderm. 3) the spreading of the mesodermal plate until a complete pear shaped, trilaminar embryonic disc is formed. 4) the differentiation of the epiblast into the ectoderm and in the final stages 5) the formation and growth of the notochord (mesoderm) and the neural plate (ectoderm). The end result is a curved trilaminar embryonic disc. The inside of our digestive and respiratory tubes are formed during embryonic folding where the ectodermal cavity practically grows over the endoderm, pulling the endodermal cavity inwards. From the endoderm develops the allantois (umbilical cord) and the umbilical vesicle (yolk sac, useless in humans). The amnios is the exterior layer of the ectodermal cavity. The inner layer (that which is part of the trilaminar embryonic disc) of the ectodermal cavity will become skin and brain during fetal development. The chorion was formed from the trophoblast.
