Question

In diploid set of chromosomes, deletion or addition of a member leads to

• A. Aneuploidy
• B. Euploidy
• C. Polyploidy
• D. Triploidy

Answer 1

The correct option is A Aneuploidy

• Aneuploidy is changed in chromosome number by additions or deletions of less than a whole set.
• The presence of multiple numbers of complete haploid chromosomal sets is polyploidy.
• The presence of three complete haploid chromosomal sets is triploidy (3n).
• Euploidy refers to the presence of more than two complete sets of chromosomes.

So, the correct answer is option A.
