1: A karyotype is created and used to identify possible chromosomal defects.

Explanation:

A karyotype is the observed characteristics (number, type, shape, position etc.) of the chromosomes of an individual or species within the nucleus of the cell (mainly eukaryotic). Karyotype tests are performed to show if an individual’s chromosomes are normal or not. The chromosomes (especially those in the white blood cells) are usually isolated, stained, and examined under the microscope. This detect if there is an abnormal chromosome, an extra chromosome or an incomplete chromosome. A karyotype can be used as a scientific report because possible chromosomal defects such as Down syndrome (trisomy 21), Klinefelter syndrome, Edwards syndrome and Turner syndrome can be identified using the Karyotype tests.
