Question

karyotypes can be studied to determine an organisms 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?
polyploidy
tetraploidy
aneuploidy
trisomy

Explanation:

• Polyploidy: Refers to having more than two complete sets of chromosomes (e.g., triploid - 3 sets, tetraploid - 4 sets). Turner syndrome is not about having extra complete sets.
• Tetraploidy: A specific type of polyploidy with 4 sets of chromosomes. Not relevant to Turner syndrome.
• Aneuploidy: Is an abnormal number of chromosomes (not a complete extra set). Turner syndrome (XO, where there is a missing sex chromosome) is an example of aneuploidy.
• Trisomy: Is a type of aneuploidy where there is an extra single chromosome (e.g., trisomy 21 - Down syndrome). But Turner syndrome is due to a missing (not extra) sex chromosome.

Answer:

aneuploidy
