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?\npolyploidy\ntetraploidy\naneuploidy\ntrisomy

Answer

Brief Explanations:

  • Polyploidy: Refers to having more than two complete sets of chromosomes (e.g., triploid - 3 sets, tetraploid - 4 sets). Turner syndrome is not due to extra complete sets.
  • Tetraploidy: A 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, missing one X chromosome) is an example of aneuploidy (monosomy for the sex - chromosome in this case).
  • Trisomy: Is having an extra single chromosome (e.g., trisomy 21 - Down syndrome). Turner syndrome is a monosomy (missing a chromosome), not a trisomy.

Answer:

aneuploidy
