Question

Which one is not related to chromosomal abnormality?

• A. Aneuploidy
• B. Euploidy
• C. Klinefelter's syndrome
• D. AIDS

Answer 1

The correct option is D AIDS

Below mentioned are all chromosomal abnormalities:

1) Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46.

2) Euploidy is a condition when a cell or an organism has one or more than one complete set of chromosomes. Euploidy occurs whenever a cell has a multiple of the haploid number of chromosomes

3) Klinefelter syndrome is a sex chromosome disorder in boys and men that results from the presence of an extra X chromosome in cells.

AIDS is not related to a chromosomal abnormality rather it is caused by HIV.

So, the correct answer is 'AIDS'.
