Karyotyping displays chromosomes in homologous pairs by decreasing length, obtained through cell harvesting, cell division induction, and mitosis arrest. It's done prenatally to test for sex or chromosomal abnormalities like Down Syndrome (trisomy 21) caused by non-disjunction.
La cariotipia muestra los cromosomas en pares homólogos de longitud decreciente, se obtiene al cosechar células, inducir la división celular y detener la mitosis. Se realiza prenatalmente para detectar sexo o anomalías cromosómicas, como el síndrome de Down (trisomía 21) causado por no disyunción.
| Text | Karyotyping what does it do: shows the chromosomes of an organism in homologous pairs of decreasing length process: -Harvesting cells (usually from a foetus or white blood cells of adults) -Chemically inducing cell division, then arresting mitosis while the chromosomes are condensed -The stage during which mitosis is halted will determine whether chromosomes appear with sister chromatids or not Will occur prenatally to test for gender or chromosomal abnormalities |
|---|---|
| Extra | Trisomy 21 - down syndrome, due to non-disjunction in one of the parental gametes, causes mental and physical delays in child's development |
