Karyotypes can be studied to determine an organism's chromosomal makeup and to detect genetic defects. patau syndrome occurs when an individual has an extra copy of chromosome 13, giving them three copies. symptoms of patau syndrome include extra digits, seizures, and cleft palate. which word would geneticists use to describe the cause of patau syndrome?

The correct answer is term Trisomy which is three copies of a particular chromosome (chromosome 13 in Patau syndrome) instead of two copies.

Explanation:

An error in cell division known as nondisjunction leads in a sex cell with an abnormal number of chromosomes results in trisomy. A trisomy is a disorder characterized by the addition of a chromosome, so the person has 47 chromosomes instead of 46.

Edward syndrome, Down syndrome, and Patau syndrome are the very common forms of trisomy. Patau syndrome is a trisomy condition that causes multiple organ defects in the individual.
