How is karyotyping related to Amniocentesis?
Need more help on the karyotyping side.
Thanks :)

Answer 1

amniocentesis is used to find fetal skin cells that can be grown in culture. A karyotype (chromosome spread) of the cultured fetal cells can then be made. Karyotypes can reveal missing or extra chromosomes and other chromosomal abnormalities.

Answer 2

Yes, but they're two different things. Amniocentesis is when you stick a needle into a prognent woman's lower abdomen and draw out some fluid that surrounds the baby. This doesn't hurt the baby. You can do certain tests on the fluid to see if the baby is okay. One important test you can do is 'karyotyping' to see if the baby's chromosomes are normal. This will tell you if the baby has Down syndrome or other chromosomal abnormality. Karyotyping can be done by taking a photograph of the chromosomes and then counting them and looking at their shape.

Answer 3

Amniocentesis takes out a small amount of amniotic fluid from around the baby. This fluid contains some of the baby's cells that have fallen off into the fluid.

Technicians can make a picture of the baby's chromosomes from the cells in the amniotic fluid. Once they have a picture of the chromosomes, they cut the picture apart in order to sort the individual chromosomes and line them up in order, largest chromosomes first. This organized layout of the chromosomes is called a karyotype, and the acti of doing this organization is called karyotyping.

From the karyotype, the technician can see if the baby has the proper number of chromosomes and if the chromosomes have all their parts. It's useful to diagnose disorders like Down Syndrome, Turner Syndrome, Klinefelters ....

Answer 4

a karyotype, which arranges all the chromosomes of a person according to size, can be derived using amniocentiesis on an unborn child. amniocentisis requires amniotic fluid to be drawn from the womb and analyzed because the amniotic fluid contains the same DNA as the unborn child. this process can identify hereditary diseases or some disorders the child may have inherited
