Question

Karyotypes can be studied to determine an organism’s chromosomal makeup and to detect genetic defects. Turner syndrome occurs when a female has an incomplete set of sex chromosomes. Symptoms of Turner syndrome include swollen hands and feet, short stature, and infertility. Which type of chromosomal mutation is responsible for causing Turner syndrome

Answer 1

Aneuploidy is the type of chromosomal mutation that is responsible for causing Turner syndrome.

Aneuploidy is a type of chromosomal mutation in which there is presence of an abnormal number of chromosomes in a cell. The chromosomes may be incomplete (missing) or excessive (extra). For example, if a human cell had 42 sex chromosomes instead of 46, or it had 48 chromosomes instead of 46, it is said to be anueploidic in nature. Aneuploidy occurs during cell division when there is improper separation of the chromosomes between the two cells. Aneuploidy is responsible for many genetic disorders including Turner syndrome.
